Indispensable and wonderful.
When this stuff disappeared from all my local Krogers, I just about cried. I love it, and use it a lot. A dab (not a dollop) is essential in tuna casserole, great in mac and cheese, yummy in tomato soup or gazpacho, splendid on veggieburgers and fries (I keep a bottle in the car!), and absolutely KILLER on pizza.
Note, though: I really do mean a dab, not a dollop. Not because of the heat, which seems mild to this old chilehead, but because of the flavor, which is mellow but extremely concentrated and quite smoky. Use restraint till you know how much you like.
Flavor, flavor, and flavor. No kidding, try it on pizza--you'll thank me! :) And price, which is generally lower in grocery stores than it is here.
