Novice question - adding spice mix to frying onions for slow-cooker curry. I'm an inexperienced cook - recently started trying slow cooker recipes as we have one and it seemed like a good place to start.

My question is regarding the prep for a slow-cooker curry.

Twice now a recipe had called for pre-frying of chopped onions, which is fine.

But then I need to add the spice mix and fry for a few minutes until aromatic.

When I add the spices, the pan becomes extremely dry and the mixture begins to stick.

I've already added the specified amount of oil, the recipe makes no mention of this happening  - is there something I'm supposed to do to prevent this - can I add water or something?

Any suggestions would be much appreciated.
