Step 1

Put 1 cup of tomato ketchup in a small saucepan and heat on medium low. When ketchup is warmed through, add baking soda and stir continuously until foaming subsides. Ketchup should look normal again.

Step 2

Reduce heat to low. Add remaining ingredients, through to water and stir until combines. Let it simmer on the stow for 5 - 10 minutes to meld flavours.

Step 3

Serve warm over sliced bratwurst with crusty bread or fries as a side.
