When you sub heavy cream for half and half, you're essentially adding more fat to your recipe. This can affect the texture and flavor of your dish, making it richer and more indulgent. However, it can also make it too rich, so use with caution!
In some cases, like in coffee creamers or desserts, using heavy cream instead of half and half can be a great way to add extra flavor and creaminess. But in other recipes, like salad dressings or marinades, the extra fat can be overwhelming. So, it's all about balance and knowing your recipe.
Here's a fun fact: did you know that half and half is actually a relatively new invention? It was first introduced in the US in the 1960s as a coffee creamer, and has since become a staple in many American kitchens. Heavy cream, on the other hand, has been around for centuries, with the ancient Romans using it to make delicious desserts.
