Fragrant ripe pears and rich honey butter are a great match for the dark, earthy flavors of buckwheat flour in these pancakes—imagine a plate of traditional blini but bigger, heartier, and laden with fruit. Choose a honey with a sweet, mild flavor, such as acacia or orange-blossom. And make sure that your pears are juicy and ripe, but not so soft that they fall apart when you grate them. If you don’t have whole-grain pastry flour, use all-purpose flour instead. The pancakes won’t have quite the pillowy texture they would with pastry flour, but they’ll have the same delicious flavor.
