Making this burnt out my old Bamix. Even if the recipe destructions say you must beat over heat for 4-5 minutes and then for a further 5-6 minutes away from heat, this still doesn’t over-ride the Bamix manufacturer’s destructions that you must not use it continuously for over 5 minutes. If you do, the magic smoke comes out and it is impossible to get it back in (thanks @greengecko29).
