For the candied almonds: Line a baking sheet with parchment paper. Heat a medium nonstick skillet over medium heat. Add the almonds, sugar and a splash of water and stir to combine. Cook until the sugar has melted and the nuts begin to caramelize, stirring occasionally, about 10 minutes. Spread the nuts out on the parchment and cool on a baking rack until the sugar hardens, about 15 minutes.
For the ricotta: Stir together the ricotta, zest, sugar and cream in a bowl until light and fluffy.
For the crepes: Whisk the eggs in a medium bowl until smooth. Add the milk, zest, butter and salt and whisk until combined. Add the flour and whisk until smooth. Cover and refrigerate for at least 30 minutes and up to 1 day.
Preheat the oven to 200 degrees F.
Heat a 6- to-8-inch nonstick pan over medium heat; spray with nonstick cooking spray or brush with clarified butter. Ladle in a scant 1/4 cup of the crepe batter; swirl the pan and cook until the bottom sets and turns light golden brown, 30 to 45 seconds. Flip and continue cooking until the bottom is light golden brown, another 20 seconds or so. Transfer to a plate. Repeat and stack, keeping the cooked crepes warm in the oven.
Spoon a heaping tablespoon of the ricotta on each crepe, roll up the crepes and serve with a sprinkling of candied almonds.
