No pork products (obviously).
I don’t keep olives on hand- if I want olives, I get good ones from the olive bar at the grocery store, and use them quickly. No jarred or canned olives for us.
Celery- Mr. Neville doesn’t like it, and can taste really small quantities of it, so we don’t use it in our cooking.
Most bottled salad dressings. I have some ranch, blue cheese, and honey mustard for dipping sauces, but usually when we want a salad dressing we make it ourselves from oil and vinegar.
No milk that is not fat-free, and no half-and-half or cream.
No dessert stuff, other than the obligatory Girl Scout cookies and Passover desserts- Mr. Neville and I are fat enough without desserts, thankyouverymuch. That means we don’t have maraschino cherries or whipped cream.
Cooking sherry or cooking wine- when we want to use sherry or wine for cooking, we use regular drinking sherry or wine.
White vinegar- we always use balsamic, sherry vinegar, or rice vinegar.
Pancake topping- we almost never make a sit-down breakfast.
Decaf coffee- I’m the only one who drinks coffee, and I know decaf for the abomination unto God that it is. We had a can of it for a while (bought for a visit by my parents), but it lasted for years, until we threw it out when we moved.
We have butter, but it’s in the freezer- we pretty much use it only for cooking, not for spreading on things.
We might very occasionally have parve (non-dairy) margarine to use with meat recipes, but we don’t have any other kind of shortening.
We don’t keep potatoes around- I had a bad experience with forgetting about a bag of potatoes in a cabinet until I found them all full of maggots.
We have mayo, but rarely use it, and don’t use it for spreading on stuff- it’s almost always for making aioli. We don’t have Miracle Whip, because that stuff tastes like mayonnaise six months past its expiration date (and I would know).
