The user wants to make cereal milk ice cream and is unsure whether to steep their cereal in milk, heavy cream, or a combination of both. Their recipe calls for equal parts whole milk and heavy cream. Steeping the cereal in both milk and heavy cream is the recommended approach to capture the flavor from both liquids as intended by the recipe. This ensures an optimal flavor infusion for the ice cream base. Subsequently, this infused mixture will be incorporated into the rest of the ice cream base ingredients.
