chutney is a sauce made with chunky fruit and spices, you can get mixed fruit chutney, apricot chutney, mango chutney, some chutney's have added chillies, so you can get hot or mild chutneys as well - very tasty - can have with just about anything, steaks, chicken, fish etc. :)
Albertsons, United, Marsh etc stock chutney, of the English brands Major Greys is pretty good, from India you get Poonjajis which is the best ! - My favorite is Poonjajis Hot Tomatoe chutney.
Monkey Gland Sauce is just a very spicy sauce made up from different sauces, spices and chutney, I think the name came from monkeying around, and has never had anything to do with Monkeys. The steak you prepare as usual, marinate, BBQ or fry.
If you can't find chutney, you can always use half a cup of apricot jam.
