OXO Good Grips Mandoline Slicer 5 "OXO (Never lets me down) Mandoline." 29 November 2020 I’ve managed for 50 years without it, so why should I need it now? Slices onions so finely for frying off for gravy. Bit of salt and butter/ oil, turn to low and leave. Add the veg water. Tad of you know what... Dentally challenged but love salads. Raw white cabbage, radish, cucumber, cooked beetroot All sliced so thinly I can enjoy them. Not good for tomatoes. I’m using it a lot. I take care to put the guard on, swill and cover straight after use.
