One cannot discuss the Old Sauces of the Cape, without sharing a recipe for that piquant sauce used in the traditional cooked onion salad called slaphakskeentjies. (The direct translation for slaphakskeentjies is small floppy heels, but one explanation for this peculiar name is from the original Dutch where “slap hakke” means without energy or spunk, refering to the onions being boiled until they are soft and without some of their original sharpness.)

Slaphakskeentjies is a delicious accompaniment to meat and is a popular side dish with a South African braai.

SOUR SAUCE FOR SLAPHAKSKEENTJIES

This sour sauce wasn’t just used for slaphakskeentjies, but also for green bean salad. The sauce was thickened with egg yolk, but if eggs were in short supply it was thickened with a little flour. Cape mustard, made from the indigenous mustard, was used. This recipe is from our Cape Winelands Cuisine cookbook, page 140.

1.5 kg pickling onions, peeled but kept whole and with root base intact
