1/2 C. warm water
4.5 tsp. active dry yeast (2 envelopes)
Pinch of granulated sugar
1/3 C. granulated sugar
1 C. warm milk
1 tsp. pure vanilla
2 eggs, lightly whisked
1/3 C. canola oil
1 1/2 tsp. salt
2.5 C. whole wheat flour
2.5 C. all-purpose flour, plus more for dusting work surface and your hands
4 C. canola oil for frying
2 C. granulated sugar, tossed with 2 tsp. cinnamon (reserve in a shallow bowl)
Lemon

In a large bowl, stir together warm water, yeast and a pinch of sugar. Let stand until it is slightly foamy (about 5 minutes). Add the remaining 1/3 C. of sugar, milk, vanilla, eggs, oil and salt. Stir until smooth. Mix in about half of flour and continue stirring, with a wooden spoon, gradually adding the remaining flour until it all has been incorporated. Flour your hands and turn dough onto a floured surface. Knead for about 5 minutes. The dough will be very sticky, but resist the temptation to add more flour. Transfer dough to a greased bowl and cover with a clean dish towel. Let dough sit covered until it rises and doubles (about 45 minutes). Lightly deflate dough and pinch off a piece about the size of a golf ball. Gently form into a ball with your hand. On a floured surface, use a rolling pin to roll out the small ball of dough into an oval shape, about 2 x 4 inches. Put it onto a lightly floured baking sheet and and cover it with a tea towel while you continue to do the same with remaining dough. Heat about 4 inches of oil in a deep-fryer (375F/190C)) or Dutch oven. Before placing flattened dough into oil, gently stretch to enlarge the oval (I stretched mine to about 4 x 7 inches), to resemble a beaver tail. Carefully slip the dough ovals into oil (one or two at a time). Fry, turning once, until golden brown, about 30 seconds per side. Carefully remove from oil and let drain momentarily on paper towels. While still warm, toss lightly in cinnamon sugar. If desired, squeeze a bit of lemon over the pastry.
