I love Mezzetta's Garlic Stuffed Olives. They're great in a dish by themselves, chopped up in some Tapenade or reclining in an ice-cold martini. I try to keep a jar in the fridge at all times. I think that they are that good. Hard to find in my neck of the woods, and a little bit pricey, but worth it. Especially when I can find them on sale.
Another brand I really enjoy (but can't get here.) is Litehouse dressings . They have a Light Blue Cheese dressing that's full of flavour and not vinegary at all, just cheesy. Their Jalapeno Ranch dressing is out of this world and I use it for my deviled eggs, adds a nice little zip. They used to have a Jerk sauce that was so awesome that I cried when they discontinued it. Well, not really, but I wanted to. They can be found in the refrigerated section in the produce department.
I also like Siljans Crispbread, but they're not widely distributed, so unless you're in a major metropolitan area or can afford the shipping costs it just isn't worth it. And since I don't live near a major metropolitan area or near a Scandinavian Deli and don't want to spend more to ship it than to buy them, I make do with Wasa Crispbreads and they do just fine.
As you may have surmised before, I'm kinda drawn to spicy food, and one ingredient I love to use in my Chile Verde is Stoke's Green Chile Sauce. I can't find it in my state, but I've been known to have a case shipped in from time to time.
There you have it, just a few of my favorite things. Well, favorite brands, at any rate.
