Oil-free pumpkin steamed cake

Overview

No oil, no burden, delicate and soft, very suitable for the elderly, children and people with gastrointestinal problems

Steam the old pumpkin and mash it into a puree. It's best to have a food processor. Anyway, the more delicate it is, the better.
Three eggs separated
Stir egg yolks, rice flour, and pumpkin puree evenly.
Beat the egg whites, add the sugar three times and beat until 9 points.
Put the egg whites into the pumpkin paste and mix gently without letting the egg whites defoam. When it's evenly mixed, pour it into the mold, cover it with plastic wrap, and steam it in a pot.
Steam over medium heat for about 40 minutes.
When it cools down a bit, it will shrink back a little, making it easy to unmold, cut into pieces and eat.
