Leeks are best used soon after harvest. Refrigerate in a plastic bag for up to two weeks.
Wash just before use. Leeks need to be washed well because soil is pulled up around the stem as they grow. There is almost always grit caught between the layers.
- Cut off the roots, the dark green tops, and any damaged outer layers.
- Slice once lengthwise. • Rinse thoroughly under running water, cleaning between each layer to remove soil and sand.
- Chop or slice as needed.
Leeks can be frozen in slices or whole lengths. Seal in airtight bags. For best quality, use within 3 months
