Cut Uniformly: Halve or quarter the sprouts so they cook uniformly and get an even crispy texture.
Dry the Sprouts Thoroughly: Make sure your Brussels sprouts are completely dry before frying to prevent splattering and ensure crispiness.

Mustard Aioli Variations: Mix in a bit of lemon juice or honey into the mustard aioli to balance tanginess and sweetness.
Garnish Creatively: Top your fried Brussels sprouts with toasted sesame seeds, grated Parmesan, or chopped herbs like parsley for added texture and flavor.
