I only use mine only for canning so not much chance of the vent getting clogged from that. I do check it every time I can, though.
Using a pressure cooker for stews and beans is handy in a hurry, or try a pork roast with a can of pineapple dumped on it.
I can have a pressure pot of beans on the table in 1 & 1/2 hours, I put my spices, onion, garlic, etc in before cooking and add salt later, as I recall they only cook 45 minutes.
Takes just long enough to make a pan of cornbread.
