Vanilla sauce is a sweet, creamy sauce made primarily from vanilla extract, sugar, and cream or milk. It is often used as a topping for desserts like ice cream, cakes, and puddings, adding a rich flavor and smooth texture. This sauce can be prepared in various ways, including cooking it on the stovetop or blending it for a lighter version. Some recipes may also incorporate egg yolks to create a custard-like consistency. Vanilla sauce enhances the taste of many dishes, making it a popular choice in both home cooking and professional kitchens.
