When I reheat last nights curry in a microwave and cover it in clingfilm, the moment I take it out, the clingfilm tightly covers all the crevices and projections of the curry's surface. It is as if there is a vacuum inside. How can this be? Surly nothing has left the covered bowl.
P.S. while the curry in in the microwave the water evapourates and causes the clingfilm to bulge, but when I take it out and the water condenses, there is less pressure inside than before I heated it.
A few months ago I went to France and had Muscles with a white wine sauce. I absolutely loved it and told my mum, who then went on to make me Muscles with white whine sauce around 8 times between then and now. The only problem is, now I absolutely hate the stuff, I dislike the texture and the taste. This happens with other foods as well. Why do we come to hate foods we formally love? What is scientifically happening in our bodies which changes the way I feel about foods?
On initial prodding, ordinary potatoes and sweet potatoes seem to
have the same consistency. But when you roast them, sweet potatoes cook
more quickly than ordinary ones. Why?
Hot food contains more heat therefore more energy. Does this mean that it will give more energy to whoever eats it or just make them temporarily hotter by heating them on the inside?
