hi, our entire kitchen is basically meat-only, except we have a dairy nutribullet that we use for smoothies. we don't have dairy dishes and don't cook dairy.
can we use the diary nutribullet to grind a cold, non-sharp item and then put that item into our meat cookware?
for example, we wanted to grind almonds in the dairy nutribullet to put into a parve recipe that we were making using our meat cookware. even if not a good practice, is this still technically permissible? if we wanted to put the almonds into a meat recipe instead of a parve recipe, does the answer change?
I once asked a similar question about a Pareve appliance and the Rov said the problem was that food can get stuck in crevices that you may not be able to clean, I think it was a hand mixer, so Rov said cover all vent holes w foil while using it with not pareve food.
