Try this recipe for meringue and maybe it will work for you.

Mix 1 tbsp cornstarch with 1/2 c water. Boil just until thick, in microwave or
stove, stirring to prevent lumps. Cool.
Beat 3 egg whites till foamy, add 6 tbsp sugar gradually,dash of salt. Beat
till stiff. Add cornstarch mixture and continue beating till mixed in. Bake

Don't bake meringue too long. Cut with a wet knife. If you live in an area of
high humidity that's a possible reason for sticky meringue. Good luck
