How to make Sweet Potato au Gratin
To make this Sweet Potato au Gratin, I used regular brown-skinned sweet potato or yams found in many supermarkets. With red-skinned sweet potatoes if you are lucky you can find nice shapes and good ones. This particular ingredient is a hit and miss. They are not also available in many supermarkets.
I was also very skeptical about the original recipe since it asked for milk and not heavy cream. Most recipes online usually required heavy cream because of texture. When heavy cream is mixed with cheese, you have a heavier and creamier consistency. But again, heavy cream has more fat than milk.
The original recipe also required fresh milk. That’s also a challenge if you don’t live in the Caribbean, on a farm, or close to one where you can find fresh milk. I opted to use regular milk instead. I also reduced the amount of milk the first time I made this recipe. Not bad at all!
The second time I change the regular milk to evaporated milk. Much creamier, and dense, and same good taste.
The recipe turned out to be good. As it is similar to many other recipes, using fresh ingredients can make a real difference.
Mixing regular milk and eggs replaced the heavy cream. The dish is light and flavorful. The ginger and nutmeg are also a good addition.
Enjoy this recipe as a side dish for your next Thanksgiving dinner or anytime you want to eat sweet potatoes.
