Broadbeans and sugarsnaps. Picking and cooking

I can't give advice on broad beans, but sugar snaps I always pick when the peas are under-developed in the pod.  This is my personal preference, it seems to give a more tender, sweeter pod.

You can always let the peas develop more on a few, vs. the less developed ones, see which you prefer.

I do briefly parboil veg before freezing.  It is OK to eat if you don’t, but blanching slows the loss of vitamins and also the enzyme action that can make veg deteriorate.  Freezing slows both processes down and blanching slows them down even further.  It is also important to cool the veg down fast after they come out of the boiling water. 

I did a load of broad beans the other day with 2 pans.  Strain the boiling water from 1 pan into the other, so ready for the next batch and get the strained beans under the cold tap.  Once you get going it is a pretty quick job to do 

With broad beans, they crop so madly, you just have to freeze some.
I have not parboiled any veg for a good decade or more.
Freezers are so more energy efficient and fast freeze works very well these days, that they freeze instantly and for me all veg I freeze stays crisp, good colour and fresh.
Found broad beans to be great frozen too.
We always save a yogurt pot with lid of small one to kept for having over with our Christmas Turkey. They are always lovely.
I use yogurt pots with lids for many veg, as they stack and sit easily in your freezer trays.
Cut parsnips, carrots, french beans, rhubarb, gooseberries all do well in them.
I do though have larger cereal pour and store tubs for the likes of peas and sweetcorn.
I also have ice cream tubs that through the summer I fill with spare strawberries and raspberries and take some neighbours other fruits that I do not grow like blackberries, black/red currants for use over the winter in cakes, puddings and mixed with homemade yogurt.

One veg I did do many years ago, was runner beans, but they just did not freeze the best.
Also, spinach is a good reliable one to freeze, but as I have pickings through the year, there is no point.
