It's done via triggers.

When unit already has some item type and he picks a certain item type, both items are removed and wanted item is created for the triggering unit (Hero).

Recipe items works pretty much the same way. There is different ways to trigger the action to happen like using spell "combine", placing items down to certain areas, buying recipe or buying another item.
It's pretty simple to make but making complicated system can be difficult.

Here's a helpful link:
Item Recipe System
If you want to see more of similar systems go to the Hive Workshop section "Spells" and search for "item, combine, recipe" or something like that.

Edit: Forgot to mention that if your map has only a few recipes you can easily do it without any fancy systems, however if the amount of recipes/combinations becomes lets say over ten I'd recommend to use/make a fancy system.
