Here you go Jan: Put 3lb of ripe tomatoes in a roasting pan and sprinkle over about 6-8 tablespoons of good olive oil, 4 cloves of garlic crushed and strew with some fresh herbs, (i use a small 'branch' of rosemary and some fresh thyme) I medium onion sliced, about 1/2 a teaspoon of salt and the same of freshly ground black pepper. Roast in a med oven for about 45mins to an hour till toms are mushy and the skins are easily removed. Put into a blender (you'll probably have to do this in batches) and blend till smooth, along with a big handful of fresh basil leaves (Only one handful required, you don't have to add it to every batch) pour into a saucepan, add two tablespoons of tomato purée and a level teaspoon of sugar. Now thin down to required consistancy with stock (veg or chicken) do not allow to boil - check seasoning and serve with round slices of French bread spread with pesto and baked in the oven while roasting the tomatoes
