Wild mushroom palmiers with green olive and truffle tapenade

Not yet rated

This stunning mushroom palmier recipe makes a great vegan canapé for Christmas, topped with lightly truffled green olive tapanade for wonderfully more-ish flavour. Certain brands of puff pastry are a vegan's best friend for the festive season – just make sure you check the label first.

I know these aren't technically the correct shape to be considered a palmier, but I think these are more visually pleasing! These simple canapés can be done well in advance and just so happen to be vegan.

For frequent dinner party-throwers, you can keep a roll in the freezer to pull out and bake with only twenty minutes notice.




Wild mushroom palmiers

Green olive and truffle tapenade


Begin by making a mushroom duxelle for the palmiers. Soak the dried mushrooms in warm water for about 10 minutes
Meanwhile, sauté the garlic and shallot in a splash of oil until translucent, then add the mushrooms and chopped rosemary and cook down until soft. Season with a pinch of salt
Transfer the mushroom mix to a blender. Squeeze the soaked mushrooms (but keep the soaking liquid) then add to the blender too. Blend to a smooth paste, adding some of the mushroom stock if it needs loosening a little. Season with salt if it needs it, and leave the mixture to cool
Cut the pastry sheet in half widthways, then spread the cooled mushroom duxelle in a thin, even layer over both pieces of pastry
Roll up the pastry into a tight roll, then wrap in greaseproof paper and place the two rolls in the freezer for about an hour, or until they are solid enough to be able to slice without misshaping
To make the tapenade, place the olives, garlic and capers in a blender and blitz to a paste. Add the oils a little at a time until you reach the desired tapenade consistency (you may not need all the oil). Season with lemon juice and salt
Preheat the oven to 180°C/gas mark 4
When the palmiers are hard enough to slice, cut into 5mm slices and place on a greaseproof-lined baking tray (leaving enough space for them to expand a little whilst cooking)
Bake in the oven for about 15 minutes, flipping the palmiers over halfway through cooking for an even bake
Serve warm or at room temperature with dollops of tapenade and fresh basil leaves
