Two ingredients and twenty minutes is all it takes to make a lemon infused olive oil that beats any commercial version. Good quality Greek extra virgin olive oil, fresh lemon peel, low heat and a little patience. That's it.
Scrub your lemons quite thoroughly and peel avoiding any of the white pith.
Place the lemon peel with the olive oil in a sauce pan and cook over a very low heat for 10-15 mins. (make sure the mixture does not boil. We want to the flavours to infuse nice and slowly)
Remove from the heat and allow the olive oil to cool down completely. Once cooled, remove the peel and pour the flavoured oil in a bottle or jar.
Store in a cool, dark place to allow the flavours to develop.
Notes
Use the best olive oil you have -- it's only two ingredients so quality matters enormously here.
Keep the heat as low as possible. If the oil bubbles or simmers it's too hot and you'll end up with bitter oil.
Avoid the white pith when peeling -- it will ruin the flavour. A vegetable peeler gives you more control than a knife.
Remove all lemon peel before storing. Never leave organic matter sitting in the oil.
Give it 2-3 days before using -- the flavour develops significantly and it's worth the wait.
