Step 1

In a large saucepan combine the tomato paste and water.  Stir in the baking soda, sugar, and spices.

Step 2

Heat the tomato paste mixture over medium heat.  This is a thick mixture and it pops and splatters, so you'll probably want to cover it, stirring occasionally.  Let it simmer for 10minutes.

Step 3

In a separate large saucepan, heat the 3 cups of milk.

Step 4

When both the tomato paste mixture and the milk are about the same temperature (just use your best estimate), combine the two by slowly pouring the warmed milk into the tomato paste mixture, stirring it as you go.

Step 5

Simmer the mixture for a few minutes to let the flavors meld together and then serve.
