April 2021 Cave to Co-op: Eidolon from Grey Barn Farm, Martha’s Vineyard, MA

Our Cave to Co-op for April 2021 is Eidolon from Grey Barn Farm in Chilmark, Martha’s Vineyard, MA — a certified organic, pasteurized, bloomy-rind cow’s milk cheese.

The Grey Barn Farm in Chilmark started with just three cows in 2009; now, there are 40 Dutch Belted ladies grazing the fields, as well as pigs, sheep, and chickens.

This cheese takes its name from the Walt Whitman poem “Eidolons:” an Eidolon is an object’s perfect form; it’s an ideal, almost unattainable. For Grey Barn, that perfect form has always been a cheese that captures the heart of the farm: one that packs a taste you could only produce on Martha’s Vineyard. Instead of a standard brine, they hand-salt and dry the Eidolon after they’ve been drained into their cylindrical form. The starter cultures in Eidolon naturally bloom over time, forming the soft and delectable white rind that distinguishes the Eidolon and other “bloomy-rinds.”

Bright and grassy with hints of apple and celery, Eidolon is Grey Barn’s signature bloomy-rind cheese, deliciously inspired by French classics like chaource and coulommiers. A rich ring of creaminess surrounds the cheese’s caky center for a unique mix of texture and flavor.

The folks at Grey Barn suggest serving Eidolon with crisp green apple, light honey, and toasted bread. Switching the apple and honey for a favorite marmalade makes Eidolon a delicious breakfast treat. And with an acidic vinaigrette, Eidolon makes a wonderful salad topping.

Eidolon, Mussels & Bacon Tart

Ingredients for Pastry

4 oz  butter
8 oz flour
2 oz freshly grated Parmesan
1 med egg, beaten with 1 T milk

Ingredients for Filling

2 T olive oil
1 red onion, finely chopped
2 garlic cloves, finely chopped
4 oz cooked bacon or pancetta, cubed
4 med eggs
1¼ cups heavy cream
3 T snipped chives
1 lb frozen cooked shelled mussels, thawed and drained, or 4.5 lbs fresh mussels
8 oz ripe Eidolon, rind removed and cubed
8 oz mixed salad leaves, to serve
2-3 T bought or homemade vinaigrette, to serve


1. Rub the butter, flour, and Parmesan together in a bowl until the mixture has the consistency of fine breadcrumbs. Add the egg mix and quickly bring it all together into a dough. Knead lightly a few times with floured hands until smooth. Shape into a flat ball, cover in cling film and chill for at least 1 hour.

2. Heat oven to 400ºF. Roll the pastry out to ¼-inch thickness and line eight 4-inch tartlet tins. Fill with grease-proof paper and baking beans, and bake for 7-10 minutes until the pastry feels dry. Remove beans and paper, then bake for 2-3 minutes, until lightly golden. Leave to cool.

3. Reduce oven to 350ºF. Heat the olive oil in a frying pan and fry the onion for 3 minutes until softened but not colored. Add the garlic and bacon, and cook for 2-3 minutes. Allow to cool slightly. Meanwhile, whisk the eggs and cream with the chives, then fold in the onion, bacon, and mussels. Season to taste. Set the cases on a baking sheet. Spoon the mix in and scatter the Eidolon over the top, pushing into the mix here and there. Bake for 12-15 minutes until the filling is just firm and golden. Serve warm with dressed leaves.
