I don't find the lemon extract leaves a flavor believe it or not. I've painted on buttercream and you couldn't taste it. I use it for luster dusting decor and the smell seems to dissipate too. I prefer it because it dries so much faster than vodka which I find really wets the surface and can leave it streaky. I have not tried Everclear which has an off-the-charts alcohol level so it could evaporate even faster than vodka.
