But pumpkin is too dense. Maybe I am thinking of a thinner consistency. I haven't tried either pumpkin or tomato paste, but I love and use a lot of tomato paste, and I have planted paste tomatoes...so...curious about how think yours is.
I don't think I would BWB pumpkin. I was reading about it (planted a lot of pumpkins this year) and "they" say that the density of the product makes it too think to get the center of the jar up to temperature. If that's an issue, is there an issue with the density of tomato paste?
Am I getting it right, that it's okay to can a thick tomato paste by PC?
I never water bath pumpkin either. Yes, you can ALWAYS pressure can the tomato sauce or tomato paste. I always water bath both, but then again I usually can my tomato paste in smaller jars like half-pints, or at largest, pints. I just would never use a quart of tomato paste in a recipe so I don't can it that way. Maybe that, plus adding a bit of lemon juice or vinegar, is why mine always keeps even water bathed. Smaller jars would get hot in the middle much faster.
I usually can my chicken bone out in pints as well, because I heard that about chicken not getting hot enough in the center sometimes.
Problem solved! ALDI has tomato paste that only includes tomatoes! Nothing else! And it doesn't give that terrible acidic flavor to sauces. I am pleased!
