Drain olives and reserve olives in the jar.

Zest the lemon. Take about 3 slices of lemon and cut into tiny pieces ensuring there is no pith.

Heat olive oil in a skillet and add garlic slices. After a minute or so when garlic just starts to turn colour, add the remaining ingredients. Heat for about 1 more minute.

Remove from heat and pour over the olives in the jar.

These are best served warm but you can also serve at room temperature. If necessary reheat olives gently in the microwave until just warm.
