Yeah only if it's used right. If you want to make a peppermint sweet like the ones you get in restaurants, that's TPA Peppermint to make it - not Cool Mint as I've discovered trying to create it - seriously tastes like crap if you do that with Cool Mint instead of Peppermint.Normally i am not into using coolants but i must say i find that Cool Mint a cracking flavour!
But in some of my recipes which I use - mainly with chocolate profiles like my Peppermint Crisp chocolate bar (it's been renamed to Peppermint Crackle), then there's Charlotte's Butterscotch mints (which works well with the butterscotch ripple).
@Timwis I only use coolant if I want a cooler feel in my juices.
