100 g Marshmallows
appr. 200 g powdered sugar
water
Maizena (corn starch)
Wet the marshmellows and microwave for one minute, at the highest effect. This will cause the marshmellows to partly melt, enabling you to stir them to a full melt with a spoon. Mix/knead in powdered sugar, until the mass is quite firm, and not too sticky, hen knead with maizena, until a non-sticky (or almost non-stiky) dough forms. Let the MMF rest in a plastic bag for half an hour before using.
Store in a plastic bag for a couple of weeks.
