  1. 1

    Halve, core and wash the sweet peppers. Dry them with a paper towel, then char the outside of the peppers lightly until the skin can be peeled off. Peel the skins off.

  2. 2

    Sterilise the canning jar by boiling it in water. Let it air dry on a paper towel.

  3. 3

    Rub a pinch of salt on one side of each pepper piece. Place a slice of lemon and about three slices of garlic with each pepper piece, then place them in the canning jar while the jar is still warm.

  4. 4

    Heat olive oil in the small pot until it is 82.2 degrees C. Pour oil into the jar carefully until the peppers are covered, and there is around 1 inch of head space. Seal the canning jar with the lid, by screwing it tightly.

  5. 5

    Place the jar in the refrigerator and leave it for about three weeks before using. Peppers will keep in the refrigerator for six months.
