Cut the tomatoes into four equal parts and pass them through a blender.

Then, add the garlic and blend it. Use a wire strainer to strain the tomato mixture into a bowl.

Preheat a non-stick pan, then add the butter and melt it. Pour the tomato sauce into it and start cooking.

When it boils, add cayenne pepper, paprika, apple cider vinegar, soy sauce, sweetener, and salt. Cook with the lid closed until thickened.

Open the lid and mix frequently to avoid sticking. Serve after allowing the thickened mixture to cool down.
