Let dry on tea towel for at least 1 hour, the longer the better
Mix spixes in bowl
Add olive oil to spice mixture
Coat balck beans in spice and olive oil mixture
Pour black beans onto a parchment-lined baking sheet and spread them into a single layer. Bake for about 45 to 60 minutes until crispy and dry
The exact bake time depends on the brand of beans, so watch closely in the final minutes, taste test, and remove when the black beans are browned but before they become very dark and hard. Allow to cool for about 10 minutes before storing; the black beans will crisp up even more as they cool. Store in an airtight container in a dry cupboard for up to 1 week.
