Um, well... I know some indications you could look for to see if it has been heated. But it's not so easy
If you live withing the EU it's easy, shops are not allowed to sell honey that has been heated. Only as "cooking honey" <--- bad translation?

All the good stuff and natural enzymes are destroyed at 38-40 degrees Celsius. (some people say 45-50 C but that is NOT true!)
If you don't live in an EU country, there are som ethings you can look for:
1. If it is liquid - DON'T buy it! If the honey doesn't get stiff it's usually heated. (unless it has the color of water. Then it could be the "virginhoney" but that is usually very expensive.)
2. It's ok if it has just a little "frosting" on the top. It's just chrystallised sugar
Uh... Well... Honey can have A LOT of consitances, smooth,creamy and murky if it's dark - then it's usually from heather, almost rock solid and light - then it's usually "summerhoney" from wild flowers like rasberry, herbs, appleflowers e.t.c., completley white - from rapeseedflowers.
But really make sure it's not liquid and if the lable says it's supposed to be used in cooking - it has been heated.
If it's really stiff - almost like wax. Then it has probably not been heated.
Did I make any sense?
