Use as many chillies as you want, but use the small ones. Chop off the stalk ends, chuck 'em in a jar.
Add as much or as little decent olive oil (over here, we have acidity levels, use as low as you can get - or as she said, nao faz mal, which means, it doesn't really matter Anything under 1% should be okay.
Put oil and chillies in a tall screw top jar, add about 250ml of whisky and leave for 3 months.
Blummin lethal it is
She actually showed me using a jar of grao, can't think what they're called in English - oh yes, chick peas. use one of those - and about a quarter of it should be with whisky. Or however much you want.
There doesn't seem to be any real amounts, just chuck it all in and see what happens................
