How do you make onion puree? And what do you use it for?
Sounds like something I want!
I'm sorry about your aquantance. I just heard this morning that my cousin has metastasized lung cancer. Very large strong healthy man otherwise, 52 years old. Stupid disease.
Yes. Stupid disease. Awful for the sufferer and for their relatives. So sorry to hear about your cousin's disease.
Onion puree is:
Onions, any kind, chopped finely and gently fried in butter (with a little oil to help prevent burning) until it is well caramelised, but not burnt. Actually, they don't need to be all that fine, because they will be blitzed in a food processor.
Add chopped garlic and stir around in the pan for a short time, but it shouldn't burn at all - or you could use roasted whole garlic and squeeze out the resultant goo.
A little salt and pepper to taste.
A spoonful of tomato puree cooked out for a minute or so (might need to add a little water at this point to stop it burning - depends on your hob and the pan you use).
At this point I usually add either some soya sauce or a vegetable stock cube for a bit of extra flavour.
Allow to cool for a short time and then blitz in a food processor, or, if you don't have one, press it through a sieve - if you use a sieve, you really need to chop the onions finely.
Put it in a sealed pot/pots and keep in the fridge or freezer. It keeps well for about 4 weeks at least in the fridge. Use it in savoury dishes about a tablespoon at a time. Very good in soups and stews (used it in the mushroom soup I had yesterday).
Quantities depend on how much you would be using and how many onions you have available. I think the secret is the butter - it helps the flavour and helps to preserve it. I use unsalted butter, then I can control the saltiness myself.
