Mathris broke as soon as I added it into medium hot oil Why did my Mathris break apart (they didn't bind together) while frying?

I was making Methi Mathris-Kasuri using 1 tsp methi, peppercorns, ajwain, salt, cumin seeds, 1 tsp besan

I added quite a lot of oil while kneading the dough
You may have added too much oil. Reduce the amount of oil, or try adding butter instead. Butter usally tastes better and binds better too
