Cut the whole beans lengthwise and scrape out the pulp. Place the seeds in a saucepan.

Finely grind the empty vanilla beans and sugar in a food processor or mincer. It is okay if there are still slightly coarser pieces of the vanilla beans in there.

Place the sugar mixture in the saucepan with the water and glucose. Bring to a boil and simmer gently for 7-8 minutes.

Allow the mixture to cool slightly, then grind again in the food processor. Pour the vanilla paste into a clean glass. If you want the vanilla paste to have as few pieces in it as possible, strain the vanilla paste through a sieve.
