Haven't tried homemade ones so don't know how they taste.
An other way of getting replacement salt, is adding it to your food. Would only apply if camping I suppose, but should 'taste' a lot better.
Years ago I remember you could get these electrolyte and glucose 'tablets/sweets', like the energy ones you get now, you'd just suck on them like a sweet.
I haven't seen them in years though.
