So I'm making a lentil chestnut soup tonight that calls for a couple tablespoons of tomato paste. I bought a tube of t paste instead of the little can thinking I will save money because I won't be wasting what I don't use tonight. Then I look at the tube and think -- wow, this tube doesn't have that much in it. Was this really a good move? Then I notice the label says "double concentrated." Does this mean it's twice as concentrated as the familiar stuff in cans? In that case, it probably is a good buy. Or is the canned stuff double concentrated as well?
