We know that food is more tastier when it is hot bbe cause it's surface tension is less than why icream is more tasty when it is cold

Answer 1

Icream is more tasty when it is cold because ice cream consists almost of frozen milk. During defrost (ice cream gets additional heat, ie. energy) ice milk melts, ice cream is changing the structure ⇒ changing the taste. Barbecue additional heating means denatured protein (meat – it is a protein), which makes it more tasty. But for ice cream heating makes it less tasty.
