King Trumpet Liquid Culture – 10 ml Sterile Syringe
Species: Pleurotus eryngii (King Oyster) | Prepared in the UK
King Trumpet is prized for its thick, meaty stems and petite caps that sear like scallops and hold a firm bite. The flavour is savoury–sweet with a gentle umami that shines in pan sears, grills and slow roasts.
About This Culture
This 10 ml syringe contains actively growing King Trumpet mycelium in nutrient broth, prepared under sterile workflow. Use it to inoculate grain jars or bags, transfer to agar, or expand into fresh liquid culture in clean conditions.
Included
- 1 × 10 ml King Trumpet liquid culture syringe
- 1 × sterile needle
- 1 × alcohol wipe
- 1 × natural hemp bag (outer packaging)
Reusable Hemp Bag
The syringe and wipe ship inside an undyed hemp bag. After pasteurising, you can fill the bag with a substrate of your choice (e.g., coffee grounds mixed with sawdust) to create a small, plastic-free gift grow kit for a friend or classroom project.
Culinary Notes & Use Ideas
- Taste & texture: dense, juicy stems that brown deeply; caps stay tender.
- Quick wins: slice “scallops” from the stem and pan-sear; roast batons with olive oil and thyme; grill skewers and finish with soy–butter.
- Pairs with: garlic, miso, smoked paprika, lemon, parsley, roasted brassicas, polenta, risotto.
Nutritional Notes
Like many cultivated fungi, King Trumpet contributes fibre and β-glucans and is studied for antioxidant activity. We avoid health claims—treat it as a flavour-forward ingredient within a varied diet.
Use
- Shake to disperse mycelium.
- Clean the injection point (grain bag port or jar lid) with the alcohol wipe.
- Attach sterile needle; flame-sterilise if working outside filtered air.
- Inject 1–2 ml per grain jar or ~3–5 ml per 1 kg grain bag (adjust to your workflow).
- Incubate grain at 20–24 °C until colonised (≈12–14 days); shake once at ~40 % if desired.
- Spawn to supplemented hardwood sawdust (e.g., 50 % sawdust : 50 % soy-hull “Master’s Mix”) at 10–15 % spawn rate.
- Fruit blocks at 15–18 °C with high humidity and ample fresh-air exchange for thick stems and tidy caps.
Storage
Store refrigerated at 2–6 °C. Best within 2–3 weeks; typically viable up to ~2 months unopened. Do not freeze.
Batch Notes
- Produced in small lots; visually checked on agar before dispatch.
- Light sediment is normal—shake before use.
Why King Trumpet Fits Local Food Systems
- Performs on supplemented sawdust, helping turn local wood by-products into fresh food.
- Moderate incubation and fruiting temperatures suit low-energy indoor production.
- Durable post-harvest texture travels well for nearby farm shops, veg-box schemes and kitchens.
