My mum always made delicious salad dressing. my recipe is based on what i think went in hers.
2 cloves of garlic (leave these in the bottom of the jar for months, and keep topping up the other ingredients as required)
125ml extra virgin olive oil
50ml balsamic vinegar
1 tbspn dijon mustard
1 tspn sugar
salt & pepper to taste
mix really well and store on the shelf (not in the fridge)
this amazing salad dressing holder has recipes on the side and when you squeeze the handle it mixes the dressing beautifully with that twisty internal bit. no guest has ever figured out how to pour it though and every guest that tries gets very embarrassed as they quietly shake it and struggle to find an opening.
