Gaufres de Liege
makes 12 waffles
6 tablespoons warm milk (no hotter than 110°F)
1/2 teaspoons granulated sugar
2 teaspoons instant yeast
1 1/2 cups (230 grams) bread flour, sifted
1 teaspoons cinnamon
2 teaspoons vanilla extract
1/2 teaspoons salt
1 medium egg
1 egg yolk
1/2 cup (4 oz) unsalted butter, at slightly cooler than room temperature
140 grams turbinado sugar, or pearl sugar if you choose
Cooking spray
Dissolve
the sugar in the warm milk; then add the yeast. Make sure that the
milk is not too hot, lest it kill the yeast instead of promoting its
growth. Place a plate or some kind of cover on top of the bowl with the
milk, sugar and yeast. Set aside for about five minutes. When you
check on it, the yeast should have bubbled up, looking light brown and
spongy.
Meanwhile, mix the sifted bread flour with the cinnamon,
vanilla extract, and salt in the bowl of a stand mixer. Pour in the
yeast mixture; then add the whole egg and egg yolk. Mix on medium speed
until it is fully combined. The dough will be yellow and stiff,
yielding only slightly to a poke.
Cover the mixing bowl with plastic wrap and let the dough rest in a warm place for about thirty minutes.
Beat
in the butter piece by piece; you do not have to wait for the prior
piece to be fully incorporated before adding the next. When the dough
has incorporated about half of the butter, the mixture will be like a
very thick, somewhat broken-up paste. If you keep engaging the mixer on
medium-high speed, the dough will eventually become a cohesive whole,
looking smoother and more feeling more elastic. Scrape the sides of
the bowl if needed.
Kneading very gently, incorporate the sugar
crystals just enough to get them evenly distributed. Work quickly so as
not to soften the buttery dough too much.
Divide the dough into a dozen equal pieces, gently forming them into balls.
Place
the balls of dough on a cutting board in a warmish place for fifteen
minutes or so. During the last two minutes of this resting time, preheat
your waffle iron until it is very warm, but not hot.
Spray the
griddles with cooking oil. Place each ball of dough in a whole square
or section of the waffle iron. Like regular waffle batter, the dough
will start to puff up. Cook the waffles until the surface is golden to
dark brown. Be sure that the waffle iron you are using is appropriately
deep, or else the interior of the waffle will not be cooked through. If
you are using a vintage stovetop waffle iron, flip the iron every thirty
to forty seconds, lifting the iron to check the rate of browning. The
browning should be gradual to allow the interior to fully develop.
Set
the waffles on a cooling rack as they come out of the iron to promote a
crispy exterior. Serve immediately with a sprinkling of powdered
sugar.
Any leftover waffles, if they are not dark brown, can be
carefully re-cooked in a toaster for approximately thirty to sixty
seconds. Leftover waffles may also be kept in an airtight container
between sheets of parchment paper, for up to three days.
