This is the whole skill of harvesting salad burnet and almost everyone gets it wrong the first time. The leaf is pinnate, a stalk carrying four to twelve pairs of small rounded leaflets with deeply toothed edges. The big handsome leaves arching out from the edge of the rosette are the oldest on the plant, and by the time they reach that size they are fibrous, dry-textured and distinctly bitter. The small, soft, pale-bright leaves crowded in the middle are young growth, and those are the ones with the clean cucumber flavor.
So pick from the inside out. Reach into the center, take the leaves that are still folded or only recently opened, and pinch or cut them at the base of the stalk. A useful rule is to take nothing longer than about four inches (10 cm) of leaf stalk and nothing that has lost its fresh bright color.
Strip the old outer leaves off at the same visit and throw them away. They are not a lesser crop to be used up; they are simply spent. Removing them opens the crown, improves airflow and drives the plant to push new central growth, so the act of clearing them is what keeps the next picking good.
| Leaf | Where it sits | Texture and flavor | Use |
|---|---|---|---|
| Unfurling central leaf | Middle of the rosette | Soft, mild, clean cucumber | Best raw; the pick of the plant |
| Young open leaf | Inner ring, bright green | Tender, full cucumber flavor | Salads, butters, cold drinks |
| Mature leaf | Mid rosette | Firm, slightly astringent | Chop finely, or use in cooking |
| Old outer leaf | Outside edge, large and dull | Tough, fibrous, bitter | Strip off and compost |
| Leaf on a flowering stem | Up the flower stalk | Harsh and dry | Do not use; cut the stem out |
When the crop is at its best, and when it is not
There are two peaks. The first is early to mid spring, when a settled plant floods out new growth after winter and every leaf in the center is tender. The second is autumn, after the summer flowering pressure has passed and cooler weather brings a fresh flush. Between them, midsummer is the difficult period: heat and any check at the root make the leaves harder and more bitter, and if the plant has been allowed to flower the crop is effectively over until you cut it back.
Winter is the quiet surprise. Salad burnet stays evergreen and keeps producing slowly through frost, so on a cold morning when the rest of the garden is bare you can still cut a handful of fresh green leaves. Growth is slow then, so pick a few leaves from each of several plants rather than stripping one; a winter plant cannot replace what you take quickly.
The first light picking from a spring-sown plant comes about ten to twelve weeks after sowing, once the rosette has eight or more leaves. Take only a leaf or two per plant that first season until the crown is properly established.
How much to take without setting the plant back
Never remove more than about a third of the living leaves at one visit. The rosette is the plant's entire engine; strip it and the taproot has nothing to work with and regrowth stalls. A well-established plant picked at a third every week or ten days will keep up with you indefinitely through spring and autumn.
Cut cleanly at the base of the leaf stalk with scissors or a thumbnail rather than tearing, which pulls at the crown and can lift a young plant out of the ground. Pick in the morning while the leaves are turgid; a leaf picked in the afternoon heat is limp before it reaches the kitchen and never fully recovers.
If you need a large quantity at once, do not strip several plants. Take everything from one plant down to an inch (2.5 cm) above the crown, water it, and let it rebuild over the next two to three weeks while you pick from the others. That way one plant takes the whole check instead of all of them taking a partial one.
- Clear the old growth first Before picking anything, strip the large dull outer leaves off and set them aside for the compost. You can now see the young growth clearly and you have already done the plant a favor.
- Take from the center Cut the small bright leaves at the base of their stalks, up to a third of the plant. Leave anything longer than four inches (10 cm) of stalk.
- Use it the same day Cucumber flavor is volatile and fades fast. Get the leaves into the dish within a few hours of cutting for the full effect.
- Store standing in water If you must hold it, stand the stalks in a glass of water in the fridge like cut flowers, loosely covered. Two days is the realistic limit.
Using and keeping the crop
Salad burnet is a raw herb. The cucumber note comes from volatile compounds that cook away in minutes, so anything simmered or roasted loses the point of the plant entirely. Use the young leaves whole or roughly chopped in green salads, stir them through soft cheese or butter, drop them into cold drinks and iced water, or scatter them over a dish at the moment it goes to the table.
It does not dry well. Dried salad burnet keeps its shape and loses its flavor completely, which is why it is rarely sold as a dried herb. Freezing is equally poor for the same reason. If you want to keep it, make a herb butter or a green oil, both of which hold the flavor for weeks in the fridge or freezer, or simply rely on the plant itself, which is the real preserving method: an evergreen perennial in the ground is a supply available on demand twelve months of the year.
Worth writing down: the date of your first pick each spring, the date the leaves first turned coarse in summer, and how many plants it took to keep you supplied. Those three numbers repeat, and after one season they tell you exactly how many plants you need and when to schedule the midsummer cut-back so the coarse period never happens again.
Do not eat leaves from a stem that has flowered, even if they look reasonable. They are dry and harsh, and the presence of the stem means the plant needs cutting back rather than picking.
