I put sugar on strawberry after few time they becom softened and juicy why ?
Strawberries should be sweet enuff.....lay off the sugar, but do add whipped cream.
That the sugar draws out moisture from the hulls of the strawberries is a manifestation of osmosis. Water passes from a region of low sugar concentration, to a region of high concentration (of sugar). We would achieve the same result if we salted the strawberries.
Just to add that we are having a very good strawberry season in Sussex, and one thing I started doing was to grind black pepper onto fresh strawberries (and serve them for desert). It might sound odd but the effect is delicious.
