Betty Bossi Manual Sauce and Mayonnaise Maker 5 "PERFECT MAYONNAISE SIMPLE TO USE!" Mrs Douglas 15 September 2019 Making perfect mayonnaise here in Mallorca. Works a dream, no effort, and whisks up mayonnaise with great texture basically it does what the product says. You really cant imagine it could work so well. Whether it is using one egg or two depending on quantity of mayonnaise you want, it still comes out perfect especially the simple way you place the oil in the holder that dribbles down into the egg itself is so clever, easier than having to hand drizzle olive oil if using a blender. Very happy with this item.
