Mother had us each mix our tomatoes, onion, cloves, bay leaf, and water in a small kettle. She had us simmer it for fifteen minutes. That means cook it very slowly, with only a little heat so that it just bubbles now and then but doesn't really boi.. Then we poured it through the strainer, the coarse-meshed one. Mother had us press the cooked tomato through with a spoon. She said we must ust all of it that could be strained. [Strain the mixture into a bowl. You keep the strained liquid and toss the spent vegetables.]
Then we each took a clean saucepan and put the butter into it. We melted that over the fire very slowly and then added the flour, salt, and paprika. We mixed it very carefully with a big spoon so that there wasn't a single lump in it. And then we added the milk and cooked it all toggether, stirring it all the time till it was creamy and a little bit thick. After it began to bubble (the fire was low so it wouldn't burn) Mother had us cook it one minute more by the clock.
We each put our strained tomato mixture back in the first kettle we had used and heated it till it boiled. Then Mother had us add the soda. This made it fizz up all of a sudden, but we stirred it around for a minute and then emptied all of the tomato part right into the hot creamy milk mixture. Mother says all good cooks know that tomato souo is likely to curdle if the milk is emptied into the tomatoes. The tomatoes must be emptied into the milk. Then we let the soup get very hot for just a minute, and then we dished it up into hot soup plates and served it with crackers that had been put into the hot overn for a few minutes to make them crisp.
