I thought the OP was asking about 'energy pills for hills'.
Yes. Get yourself down to your local Indian Sweet shop. They will let you taste before you buy.
The stuff that looks like white Duplo Bricks with green spots is Pistachio Barfi.
Made with Condensed milk and sugar, heated and allowed to solidify.
Actually quite easy to make at home. It can be cut into bite size chunks and is, unlike Kendal Mint Cake, soft enough to 'melt in your mouth'.
But watch out, the stuff is addictive.
Damn! that's something I've not considered as cycling food. Beats figs.
