Sweet potatoes
Instructions
Wash the sweet potatoes in a bowl of water, don't scrub or peel: the skin protects sweetness and aroma.
(Optional) Steam gently for 30 minutes at 105°C (but remove 30 minutes from roasting time).
Roast them 160°C (320°F) for 80 min: low heat converts to sugar, forming the base for sweetness.
Then roast 10 mins at 230°C (450°F): high heat brings aromatics, inside turns creamy.
Let cool unwrapped
Wrap before putting in fridge: cooling converts starch into "resistant starches", which moderates blood sugar spikes.
