mayonnaise

[Phteven]

ooh I've got some lime and coriander in the fridge at the moment. Imran doesn't like chilli so I can't put chilli in it.

Garlic and lemon juice is nice too. I always add a bit of sugar to home made mayo.

I do think the mustard sounds good too. Or even a little horseradish for a bit of zing!

Seeded mustard here, goes down a treat.

use a different oil, or combo of oils. Peanut oil is a good one, flavoured oils work really well.
Champagne vinegar also gives a nice flavour.

[Rouge]

Pure Truffle Oil
Tarragon Vinegar
Pesto (at the end)
Garlic

I like to add fresh lemon juice and salted baby capers (rinsed and dried first). Yummy with chicken or tuna!
