Are yams and sweet potatoes the same?
In many US grocery stores, orange-fleshed sweet potatoes are often labeled as “yams”. True yams are starchier, drier, and less sweet, and they are more common in international markets. This recipe is written for the sweet potatoes most people buy in US stores.
Should I boil the sweet potatoes first?
Not necessary here. Baking them in a covered dish makes them tender without waterlogging the flavor. If you are in a hurry, you can microwave whole sweet potatoes until just tender, then slice and glaze, and bake uncovered to caramelize.
Can I make these ahead?
Yes. Bake them fully, cool, and refrigerate. Reheat covered at 350°F until hot throughout. If the glaze looks tight, add 1 to 2 tablespoons water or orange juice before reheating.
How do I keep the glaze from getting gritty?
Keep the heat at medium-low and stir until the sugar is fully dissolved and the glaze looks smooth with no visible granules. Avoid a rapid boil, which can encourage crystallization. If you still see graininess, take it off the heat and keep stirring for a minute, it often smooths out.
Can I reduce the sweetness?
Absolutely. Cut the brown sugar to 1/3 cup and keep the salt. You will still get that glossy finish, just less candy-shop.
Marshmallows, yes or no?
Yes if you love them, no if you do not. If using, add them at the end so they toast instead of melting into a sweet fog.
