With all the lovely produce we are getting from Paddy every week, there will inevitably be times when you have too much to eat right away. This might especially be the case over the coming months as we reach the end of the growing season and perhaps are lucky enough to have some of our own home grown produce to add into the mix!
We thought it would be useful over the next couple of newsletters to give you some ideas of the different methods which are available to store your vegetables and fruit for year-round indulgence. We will look at a number of the more common approaches including freezing, natural storage, drying and Jams/Pickles/Chutneys.
We will also include some recipes for jams, preserves and chutneys for those of your creative enough and brave enough to make your own! (For those of you who aren’t, I can seriously recommend Paddy’s jams and chutneys – which are available at the market every week!). This month, we will start by looking at Freezing.
Freezing Vegetables
The key to freezing vegetables is to blanch them first. Blanching is just another name for scalding – a quick immersion in boiling water – and basically is a way of preserving the colour and flavour of your vegetables. Frozen vegetables which have been blanched also retain more vitamin C than those that haven’t. Generally aim to use your frozen vegetables within six months of freezing.
What equipment will you need?
A big saucepan – big enough to hold 3-4 litres of boiling water
A net, basket or strainer for immersing the vegetables in the boiling water. Could be a chip-pan basket, a simple muslin bag, or a nylon wine-straining bag.
A plentiful supply of really cold water. For example, a big batch of ice cubes and a big basin of cold water. You can add more ice cubes as they melt to keep the water really cold.
How to blanch your vegetables
Wash and clean your vegetables, then prepare as shown in the chart below (if it’s not listed, choose the type of vegetable nearest to the one you are freezing, and go by that, adjusting for size difference if necessary).
Bring 4 litres of water to a good fast boil.
Weigh out 500g of vegetable and lower it into the boiling water in your strainer. Wait till the water comes back to the boil, then start timing straight away. Timings for the different vegetables are listed in the chart below.
Watch the timing carefully. Don’t let the temptation to ‘just get on with something else’ distract you from what you are doing, or you will end up with mushy vegetables.
As soon as the time is up, take the vegetables out of the hot water and plunge straight into the cold water. Leave them there for the same length of time you blanched them for. If you don’t cool properly, the vegetables will carry on cooking, with the same disappointing results.
Remove from the water and put into your colander or other drainer and leave to drain thoroughly. When they have stopped dripping, you can choose to open freeze or pack in portions. Open freezing is the best method—just spread the vegetables on shallow trays (try not to let them touch each other) and put into the fast freeze section of your freezer. When completely frozen, pack into polythene bags, label and put into the regular vegetable section.
NOTE: There’s no need to change the water for every batch. You can do 6-7 consecutive batches of veg in the same water (bringing it back up to the boil each time, of course) and in fact this helps to retain the vitamin C content of the vegetables.
Freezing your garden produce
Freezing food is fast and easy – and is actually one of the oldest methods known to mankind to preserve food. There are several tips to keep in mind:
- Use produce that is ripe but not overripe. Check the produce for blemishes or bad spots.
- Make sure it is clean and rinsed well.
- Most produce freezes better and has a better taste if it is blanched first
- The fresher the food you freeze, the better the flavor will be when you come to defrost and eat it. It’s best to harvest small amounts of produce at a time and freeze on the same day, than to harvest everything in one go and freeze the next day.
- You can use plastic containers, cardboard containers or freezer bags.
PREPARATION, BLANCHING AND COOLING OF VEGETABLES |
|||
Vegetable | Preparation | Blanching and Cooling time (same for both) | |
Asparagus | Wash asparagus and remove woody portions and scales of spears. Cut asparagus into 6”
Generally asparagus does not work too well as a frozen vegetable – making it into a soup and freezing this is better. |
Thin stalks – 2 minutes.
Medium stalks – 3 minutes. Thick stalks – 4 minutes |
|
Aubergines | Wash, cut into 1 inch slices.
After blanching and cooling, dry on absorbent paper towels. Pack in layers, separated by non-stick paper. |
4 minutes | |
Beans (French or Runner) | Leave small French beans whole. Runner beans should have strings removed, ends cut off. Cut into 2.5-5 cm (1-2″) lengths (best for flavour) or slice if preferred. | Whole beans and bigger pieces – 2 minutes. Sliced – 1 minute | |
Beans (Broad) | Choose small, young beans. Pod. | 3 minutes | |
Broccoli | Trim to even lengths with compact heads and cut off any tough stalks. | Thin stalks – 3 minutes
Thicker – 4 minutes |
|
Brussels sprouts | Trim off outer leaves to achieve small tight sprouts evenly sized. | 3 minutes | |
Carrots | Leave small young carrots whole, slice or dice larger ones. | Small or whole – 5 minutes. Diced or sliced – 3 minutes. | |
Cauliflower | Separate into small sprigs (florets). Wash well. | 3 minutes | |
Courgettes | Choose young ones. Wash and cut into 1
2.5 cm (1 inch) slices. |
3 minutes | |
Leeks | Remove outer leaves. Trim ends. Wash well. Cut into 2.5 cm (1″) slices. | 2 minutes | |
Mushrooms | Wash and dry well. Do not blanch in water – instead sauté in butter, cool, drain, then freeze | ||
Onions | Peel, slice or chop. | 1 minute | |
Parsnips | Choose small young ones. Scrape, wash, slice or dice. | 2 minutes | |
Peas | Only very young tender ones should be used. Sort carefully. Peas freeze really well. | 1 minute | |
Potatoes, New | Potatoes are best frozen in a cooked form. | ||
Potatoes, Chips | Peel, cut into chips. Use oil to deep fry for 2 minutes. Cool on kitchen paper. Open freeze. | ||
Spinach | Use young tender leaves or remove tough midrib of older leaves. Wash well. | 2 minutes | |
Swede | Remove peel, cut into cubes. | 3 minutes | |
Turnips | Remove peel, cut into cubes. | 3 minutes |
Freezing Fruit
Fruits are quite easy to prepare for freezing as they do not require blanching. However, fruits that are frozen are generally only best used for jams/chutneys/smoothies or for use in pies and puddings. Fruits will generally keep for up to a year in the freezer. Citrus fruits and fruit juices are best consumed within six months.
The initial preparation is just as you would before eating or cooking. Sort through, remove any fruits which are damaged, and wash. Remove any stems and stone where appropriate.
There are two main ways to freeze fruit – dry-freezing, or Puree.
Dry-Freezing
Also known as open freezing, this approach is best for small whole berries, which can be washed without breaking the skin or for fruits that will be made into jams/pies.
For example: gooseberries, blueberries, rhubarb, redcurrants, raspberries, strawberries or blackberries.
Method
1. Wash hard skin berries in very cold water, which will firm up the skin and then dry them with kitchen paper. Soft fruits should not be washed before freezing.
2. Place the fruit in a single layer on a baking tray lined with a piece of greaseproof paper.
3. Place the baking tray into the freezer, making sure that the tray is flat and freeze until the fruit is solid.
4. Remove from the freezer and transfer the fruit either to a rigid container or into polythene freezer bags.
Fruit purée
Puréeing fruit before freezing is most suitable for fruit that is not in its prime condition or for fruit that is overripe. For example: apples, apricots, plums, strawberries, gooseberries, raspberries, pears, blackcurrants, rhubarb, blackberries and damsons.
Method
1. Wash and prepare the fruit by peeling and removing the pips and blemishes.
2. Cut the fruit into slices if whole or larger firm fruits.
3. Place 1 lb (455 g) of fruit into a large saucepan with 4 tbsp of water. The water is only required in order to prevent the fruit from sticking to the bottom of the pan. Cover the pan with the lid.
4. Heat gently and simmer until the fruit is soft. Stir occasionally.
5. Stir in 3 -4 oz (85 – 115 g) of caster sugar.
6. Continue to cook and stir until the sugar has dissolved. Do not bring to the boil.
7. Allow to cool slightly and then process in a food blender or processor. Alternatively, pass through a fine sieve.
8. Pack into plastic containers leaving a little room at the top for expansion.
9. Freeze and use within 6 – 8 months.
Freezing Herbs
You can preserve most of your garden herbs by freezing. When storing fresh herbs in your freezer, it is best to first chop the herbs as you would if you were going to cook with them today. This will make using them later easier. Spread the chopped herbs on a metal baking sheet and place in the freezer. This will ensure that the herbs freeze quickly and will not freeze together in a large clump. Once the herbs are frozen, you can transfer them into a plastic freezer bag. They should last for 12 months like this.
Another approach which can be used when preparing for storing fresh herbs in the freezer is to store in ice cube trays. You can measure out typical measurements, like a tablespoon, of the chopped herbs into ice cube trays and then fill the trays the remaining way with water. This is a good way how to keep cut herbs if you plan on using them frequently in soups, stews and marinades where the water will not affect the outcome of the dish.
