Hi Fat Les
Terry actually mentioned adding the garlic cloves to the onions in a post after George had typed up the first draft, and then George added it in.

But he did hint that it was optional.
Stew - 3 litres of water?

Terry mentioned 3 pints - but that's interesting, because I used three pints and ended up adding more to water the base down at the end.
So many people are saying this is a good base. Perhaps I've just got stuck in a rut trying to replicate something else. I'll have to try it again. But I'll definately back off on the coconut.
I did use coconut block when I tried Terry's base, but something I've been using recently (out of necessity, as the shop had sold out of coconut block at the time) is creamed coconut in sachets. You get it in packs of 4 x 50g sachets, and pop what you need in hot water to soften it before cutting the sachet open. It seems to blend in better than the block, and I've added 100g of it to an 8 onion base without overpowering it before, so perhaps I'll try that.
