Step-by-Step Instructions (Procedure)
-
Preparation and Cleaning
Wash the sweet potatoes very well under running water to remove any traces of dirt from the skin. Dry them carefully. It is vital to choose pieces of similar size so that the cooking time is the same for all of them.
-
The Wrapped Secret
Wrap each sweet potato individually in aluminum foil. This allows them to cook in their own steam, keeping all the moisture in and concentrating the natural sugars.
-
Slow Roasting
Preheat the oven and add the sweet potatoes. Bake for about an hour at a moderate temperature of between 140ºC and 150ºC. Low, slow cooking is the key to transforming starch into maltose, achieving a plump texture and an intensely sweet flavor.
-
Cooking Check
Once the time is up, pierce one of the sweet potatoes with a skewer. If it slides in all the way to the center with complete ease, they’re ready! Remove from the oven and let cool on a wire rack.
Chef's Tips
-
Storage: They can be eaten fresh to warm you up, or kept in the fridge to eat chilled; this latter option brings out their sweetness even more.
-
Versatility: They are an excellent base for purées, stews, or the traditional Panellets (you can use our Levadura Natural Castelló for your creations).
-
Kidney Health: Due to their oxalate content, people with kidney failure or bone problems should moderate their intake.
How do you prefer to enjoy your roasted sweet potatoes: fresh out of the oven to warm up, or chilled as a nutritious snack?
