Is it safe to blend hot liquids in the BL660?
No, you should not blend hot liquids in the Ninja BL660. The manual explicitly states 'Do not blend hot liquids' as a caution, and notes that when blending sauces and soups, they must be cooled to room temperature first as Ninja containers are not intended for hot blending. (Pages 2, 7, 12)
