Title: What do you do with left over tomato paste?
Question: I sometimes make sauces that use tomato paste. The problem is that usually I need only one or two tablespoons and I don't know what to do with the rest of the can. The smallest can I could find is 6 oz. and while it only costs 50 cents, I hate the thought of the rest going to waste. It's also not particularly flavorful.  Any ideas?

Answers:
sents: text: This isn’t really an answer to your question, but I have found that Amore brand tomato paste has better flavor than canned tomato pastes and it comes in a resealable metal tube, which you can store in the refrigerator and take out whenever you need a tablespoon or two of tomato paste.
text: It’s also more expensive than canned tomato pastes but you actually get the opportunity to use all of it rather than just a spoonful or two.
text: America’s Test Kitchen reviewed tomato pastes (subscription required link) and came to the same conclusion: Sold in a 4 1/2-ounce tube and priced at $2.49 (considerably higher than other tomato pastes), Amore Tomato Paste shined in our initial from-the-tube tasting—no cooking, no sauce.
text: Tasters described the product as “intense” and “fresh,” which may be because of the fat it contains.
text: It also scored points because of its tube packaging.
text: Just squeeze out what you need and store the rest in the fridge.
text: No fuss, no waste.

sents: text: I freeze it in ice cube trays or silicone muffin cups, then pop them out into a ziploc bag once they're frozen.
text: It's much cheaper to buy a big can and portion it up like this than to use the tiny cans or tubes.

sents: text: I always freeze it .
text: (zip-lock freezer bags, although at the price your quoting, wasting it might almost be cheaper :) )

sents: text: Personally I'd just eat it.
text: Toast some bread, stick some paste on top and then a little cheese, perhaps a bit of EVOO.
text: Perhaps a little basil if you have it.
text: Essentially a mini pizza - brilliant snack IMO.

sents: text: I buy tomato paste in a squeeze tube for that same reason.
text: I used to buy the can, and freeze leftovers in 1 tablespoon portions.
text: I'd toss one or two in soups or stews for a little bonus flavor.
text: I've been known to toss the remainder of the can into a bread recipe with a bit of dried basil and garlic.
text: For a simple side dish, I have sauteed some onions and garlic, added the remainder of the can of paste, then toss in an undrained can of french style green beans, and simmer for 15-20 minutes.
