The wife makes small amounts as we use them ... So there is nothing to save ... Just use a little screw top jar to add the oil and vinegar in with whatever else you want .. Then shake it up.... Hay presto a dressing is ready in seconds ..
If your thinking of home made Mayo the wife tends to keep it for no more than a day or two .. But again she only tends to make as much as we need for the meal.
Hope this helps
Yes I have hens ! The wife also paints with the raw egg yoke ..mixes it with some sort of colour and she tells me it's a very old and traditional way of painting ! O and also used as a hair conditioner!Mayo is likely to contain uncooked egg yolk, so that's the reason for the much shorter shelf/fridge life.
I make mine in advance as I have so much each day! Waitrose have an excellent plastic container for oil dressings with measurements on the side. So its so easy. I never put it in the fridge. My thoughts are if its on the shelves in supemarkets then why should I put in the fridge.. The bottle also has a flip back poured which is so much better than the plastic/metal small pourers that to shake up you have to try to put your finger over the metal pourer bit.
Same with eggs, they are better stored at room temperature.
My recipe is:
1/3rd wine vinegar
2/3rds oil
1 teaspoon maille wholegrain mustard
1teaspoon lazy garlic
2 teaspoon meditereanean dried herbs
1 teaspoon honey
I have 1/2 a litre a week of this dressing.
I make my dressings fresh and don't buy them. I would never use honey, sugar or artificial sweeteners in dressings. If I have enough leftover dressing for the following day I would store it the fridge but I'm better at quantities now than I used to be.
I can't give you an actual recipe because I don't measure everything. Generally I start with the juice of half a lemon, then add olive oil and taste to make sure it's not too tart, then add a teaspoon or so of mustard (pref the one with seeds). OH is gluten free so for us that means Atkins & Potts. If I don't have a lemon (rare) then I will use Aspall's organic vinegars eg cyder. I whisk the oil and vinegar until they are totally blended together (a fork will do) and often add in finely chopped fresh herbs eg chives, parsley, tarragon, mint, basil, sorrel. Sesame oil is good so is walnut oil. My best tip would be to err on the side of oil until you feel confident, because what works as one teaspoon can feel overwhelming as a dressing.
