Is the use of emojis somehow a "new generation" thing or what is going on? I see it literally everywhere since the last year or so, especially from 'indie' or startups.
To freeze 100g of carrots requires 100g x ~80cal/g (the enthalpy of fusion of water) = 8 kcal. i.e. 16 kcal to freeze and thaw again. Given the inefficiencies of the fridge and your heating method, you are probably wasting more energy than is actually in the carrots.
