1-1. I never noticed a big difference in the consistency of canned v. tubed. Maybe some brands are very dif? But if it looks/feels the same as canned, I treat it the same.

would water need to be added to thin it out if it's twice as concentrated?

I've read in the past (maybe Cooks Illustrated?) to ignore the 2x concentrated bit and use it as normal 1-1. The great thing about the tube is that it stays fresh in the fridge.

I'm so glad you asked this, Alan! I had exactly the same question. Can't wait to see what the consensus is.

Agree with DanielleM. Leftover canned tomato sauce is extremely quick to spoil in the fridge and the tubed product keeps well. Need an entire can - canned is more economical. Small amount - tube.

Eh, I always use a can. I scoop whatever's left over into a sandwich bag, flatten it, and freeze it. Then I can break off a chunk whenever I make burritos, soups, sauces or whatever needs a spoonful or two for flavor or thickening. I do the same for chipotles in adobo sauce.

I've always subbed 1:1 as well and everything has turned out as it should.

But I agree with abbyloving. There's no waste if you just freeze any leftover paste from a can. As soon as I open a fresh can and use what I need, I immediately freeze the rest of it. I don't even bother storing it in the refrigerator at all.

BTW, does anyone know if there's a lining in the tomato paste tube like there is in the can?

I prefer buying tomato paste in a glass jar these days but what I said about freezing with the cans applies equally to the jar.

I've never used the tubed typed. How long does it last once the package is opened?

I've used tubed tomato concentrate for years and I always use it to taste. Different tubes from different manufacturers can have different concentration but tasting it always works rather than relying on a ratio.

Apartmentalized, I'm wondering the same thing. I have a tube in the fridge that I opened about 6 months ago. It seems like it's still good, but I'm afraid of risking it.

A store here in Chicago that does mail order. Amazing items and quality throughout, but one stands out. Tomato Powder. It's got a long shelf life, comes in a screw top container and can be used (with water) to make a paste or a sauce in a pinch. Not to mention it been fantastic sprinkled on lots of things. Check it out.

@G&D -- my co-op sells tomato powder in bulk! Thanks for the tip, I'll check it out for sure.

I bought a few tubes when my co-op had a special on it. I use as 1:1, but only when I need a small amount. When I need a lot, I just use the canned.

Half the amount of the canned variety as its x2 concentrated...

It is more concentrated??? I had no idea. I just assumed it was the same but just in a more compact and user friendly packaging. I always subbed 1:1 with no noticeable difference. Oh well.

I just use the tubed stuff if I only need a little, and I buy the more economical canned if I need a lot.

You can make your own tomato powder by pulverizing dehydrated or "sun-dried" tomatoes... Yum!

I always buy the can because it is more economical and I've never noticed a flavor difference between it and the kind packaged in a tube.
When I open the can, I scoop tablespoonfuls onto a plate and stick it in the freezer while dinner is cooking. When dinner is over, I toss the frozen lumps into a ziploc and have pre-measured tomato paste ready to use anytime.
