Plant oils need an emulsifier, not a solubiliser. Examples:
- Gelatin
- Agar-Agar (vegetarian alternative to gelatin; not sure of spelling)8
- Egg Yolk (but contains lecithin)
- Mustard (will mustard oil/extract do? don't know)
- Milk (Will buttermilk work? don't know)
- Will honey work? Don't know.
