Icecream or to be more precise anything with crushed ice. I always loved them had to give up after toothache intervened, that is a price for eating too much sweet and not taking care of dentures for ages. I started paying attention to them after they resigned. 😉
When we were kids there was a street- food rampantly available in north India, absolutely totally forbidden! But who cared!
The vendor used to have a huge slab of ice, he used to grate that ice and then add a few syrups on that grated ice and sell, boy we loved that we called it malai ka barf, that is hindi of ice cream.
When I shifted with my elder sister lucky for me she loved ice cream too and had a huge collection of syrups, squashes in her fridge, always and we utilized that, we used to crush the ice cubes, add too much sugar and enough syrup/squash, it tasted quite heavenly, I have eaten it later too, it tastes good!
