Don’t ever throw out your squished lemon rind, or an old lemon, use it clean your bowl and lid! This is a good tip if you’ve been cooking with a lot of onions and your bowl & lid starts to smell a little.
Use the lemon to wipe around the inside of your lid then put it in the bowl, and fill the bowl with boiling water to just above the blades.
Gradually turn dial from 2-8 and grind the lemon for about a minute.
Tip out the contents, dry your bowl and it’ll now be nice and shiny and smelling beautiful.
