The stuffing that I do has chopped bacon in it, but it is easy to leave it out. It works equally well as a stuffing in poultry, or baked separately. It can also be made in advance and frozen, just defrost the day before.
30g butter or oil
half an onion finely chopped
half a pack of chestnuts, crumbled (Merchant Gourmet)
25g fresh wholemeal breadcrumbs
1 tablespoon fresh herbs chopped, equal proportions of parsley, sage, thyme
salt and pepper
enough hot water to combine ingredients into a firm mixture.
Fry the onion in the butter or oil, when soft remove from heat and set aside to cool. Crumble the chestnuts by hand, this will give some chunks and some finer bits which add to the texture. Make breadcrumbs, if you have no food processor you can simply tear the bread by hand into tiny bits. Chop herbs. Add all ingredients to the onion in the frying pan, and mix well, adding the hot water gradually to achieve the required consistency.
I usually put some in a freezer bag for stuffing the chicken, and put the rest into a shallow oven-proof dish to bake separately. I smear some butter over the dish to grease it and a little more over the top of the stuffing, and cover it before freezing.
The amount in the dish is approximately 4 portions, the amount in the chicken is about two handfuls. A turkey will need more as it's bigger, but only stuff the neck. You can put half an onion or apple in the body cavity with a small bunch of fresh herbs to add flavour and moisture.
If anyone who's reading this wants to add the bacon, the amount for the above stuffing is 60g.
