If I chuck chicken pieces, pots, parsnip, onion, carrots in the oven with a stock cube and water for about an hour and a half will it make a yummy chicken stew or be an inedible mess? How about sweetcorn? can I chuck that in as well? All the recipes I've looked at use celery and leeks and I have neither. Help! Need to feed the children and need to use up the above ingredients.
