They sure do! At least if you add some other things.
My typical pasta sauce is composed of the following:
Pasta sauce (ragu, etc)
Ketchup
Sugar
Heat it up and mix it. Very nice.
However tonight I realised that I had ran out of pasta sauce. Whatever was I to do? I briefly considered playing with ketchup and spices, but I don't have anything except oregano....hmm. So I looked through my dry food storage area -- sugar, salt, ketchup, sweet & sour sauce...I briefly considered it, but the consistency was bad. Then I saw it.
BBQ sauce. Amazing. I grabbed the two bottles, sprayed ketchup all over a sauce pan, and heated it up. I then added about 1/3 more bbq sauce, sprinkled it with sugar, and mixed it up. Amazing!
I now have a container of pasta sauce for later.
So the topic here is: when and if you cook, do you experiment with things, or do you just cook the way you were taught/experienced at? Usually I cook the same thing every night -- it's easy, simple, and I don't have to think more than 'I'm hungry'.
