FAQs
Have you watched Clarkson's Farm?
No.
Do you offer delivery and/or collection?
For our fresh mushroom punnets, we offer collection from our Grow Room in Penryn (directions here). Please contact us for times, to make sure we'll be there.
We also offer free delivery in the Falmouth and Penryn area for orders over £20.
You can also find us Tregew Food Barn - our next dates are on the homepage.
All our dried mushrooms, liquid culture and merch can be posted, and the relevant shipping price is attached to each product.
What are your collection / delivery days?
Our delivery days are currently Tuesday mornings and Friday mornings.
Collection is 10:30am - 1pm on Mon, Wed or Thu, but we do have more flexibility around this, so if you need to collect at a different time, please contact us.
How do I pay for my mushrooms?
The easiest way to pay online. But if you're collecting, we accept either in-person card payments or bank transfers.
We don't accept cash I'm afraid, unless you come with the exact amount.
How should I store my mushrooms?
All of our mushrooms are best enjoyed fresh, so our advice would be to not store them, but eat them!
However, if you are going to store them, in our opinion, the best way to keep them is:
- In the fridge in a paper bag, not wrapped too tight. This is why we package our mushrooms this way.
- If you have lost the paper bag they were delivered in, store them in the punnet or a bowl covered with a piece of kitchen roll.
- Keep them away from the edge of the fridge (so they don't get wet), and the back of the fridge (so they don't get frozen).
- Keep them away from strong smelling foods, as they'll absorb the flavour, and nobody wants banana flavoured mushrooms.
- Whatever you do, don't wrap them in plastic or put them in a tupperware box, as they'll turn into a sweaty mess.
Can I eat my mushrooms raw?
When it comes to Oyster mushrooms, technically, yes. However, all our strains of oyster mushrooms, while they are unlikely to do you any harm raw, taste way better cooked. We'd recommend cooking them for this reason.
Fresh Lion's Mane can again, technically, be eaten raw. But it doesn't taste great, and Is far nicer when cooked. Cooking also helps release all the good stuff. The exception to this is dried Lion's Mane, which can be added directly to smoothies etc without cooking.
Allergens
If you're allergic to mushrooms, firstly bad luck, and secondly, you obviously shouldn't be consuming our produce.
For other allergens, you should be ok with our fresh mushrooms. However, please be aware that we grow them on substrate that contains wheat straw & soybean husks, so there is a small chance that traces of wheat, gluten & soy might be found on the mushrooms.
Our pouches of dried mushrooms are packed in an environment that handles other foodstuffs, therefore these may contain traces of celery, cereals containing gluten (such as wheat, rye, barley & oats), mustard, peanuts, sesame, soybeans and tree nuts.
Is it all vegan?
Yes. We're vegan, the mushrooms are vegan, even our dog is vegan.
Some growers use substrate that contains animal products, such as sheep's
wool. However, not us, we use no animal products anywhere in our business.
Are your mushrooms organic?
No. While in the growing of our mushrooms we adhere to organic principles (we don't use any chemicals, pesticides or nasties), because the variety of mushrooms we grow require such a wide variety of substrates, we cannot source everything from certified organic suppliers.
What do you mean by "growing seasonally"?
As a business we're keen to have as small an ecological footprint as possible. Some mushrooms love warm temperatures, others love it cool, and in order to avoid using unnecessary energy to cool or heat our growing space, we grow the cooler loving species at the cooler time of year, and the summer loving fungi when the air temperature is warmer.
Are your mushrooms magic?
When it comes to taste, texture and the amazing health benefits they bring, absolutely. However, none of our mushrooms are psychoactive. Sorry about that.
Where can I learn more about mushrooms?
Two excellent places to start are the movies 'Fantastic Fungi' (available
on YouTube) and 'Fungi: Web of Life' (available in the UK on BBC iPlayer).
If you're interested in learning more about mycology, we'd recommend "Growing Gourmet and Medicinal Mushrooms" by Paul Stamets, the excellent "Radical Mycology" by Peter McCoy and "Entangled Life" by Merlin Sheldrake (cheaters hint: the audiobook is a tad easier to ingest than the book!).
