For others, the butter board has inspired them to try an assortment of boards.
"OK, but I'm going to try a hummus board, dessert cookie dough board, and every dip on a board now," someone said.
Another person says, "I get it but perhaps an Avocado board."
How to make a butter board
"Then, drizzle some honey. Grate some lemon zest. Scatter some edible flowers or some chile flakes. Add figs, maybe radishes. That, and flaky salt, artfully mask reality. Serve it with bread."
Where did the butter board come from?
While Justine has elevated the status of the humble butter board, she says she got the idea from chef and cookbook author Joshua McFadden.
A butter board appears in his book Six Seasons: A New Way With Vegetables which he wrote with Martha Holmberg.
The secret to a great tasting butter board
Speaking to The New York Times, Joshua says the key to an excellent butter board is mixing up the flavours.
"Don't try to make it all taste the same," Joshua says. "Find pockets of sweetness, pockets of salt."
