How do I store leftover Purple Okinawan Sweet Potato Mash with Coconut and Ginger?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep coconut milk (full fat) from drying out.

Can I substitute ingredients in Purple Okinawan Sweet Potato Mash with Coconut and Ginger?

How do I scale Purple Okinawan Sweet Potato Mash with Coconut and Ginger for a different number of people?
