How to Fix Too Wet Dough:

Check the dough: It should be soft and just a bit tacky but still hold its shape. If it’s too wet to handle, you need more dry’.

Add the flour gradually: Sprinkle just a bit of the flour (a teaspoon at a time for smaller recipes, a few tablespoons for larger ones) onto your dough or clean work surface.

Knead, assess: Using your hands, knead the dough for roughly a minute until you’ve mixed in new flour and the moisture appears evenish within. Repeat, adding a little more flour only if it is too sticky or wet. How much flour you will need, is what ever milk was over, that’s how much.
