Heat a small frypan over medium-low heat. Add the oil and the walnuts, toast for 4 minutes, then add half the honey and the salt. Cook for another 3-4 minutes, tossing a few times. Remove from the heat, transfer to parchment paper and let cool. This will cool and become a Walnut Brittle. When cool, roughly chop.
Carefully remove the tops of the strawberries, making a flat, slightly indented top—a place for the ricotta to sit on. Slice a thin slice off the bottom of each strawberry, so that the strawberry will be able to sit flat on a plate or platter.
If necessary, mix ricotta with a couple of tablespoons of milk, cream, sour cream or yogurt. Dollop 1 tablespoon of ricotta on top of each strawberry. Repeat with all the berries. Drizzle all the ricotta-topped berries with the remaining honey, and sprinkle with orange zest and Walnut Brittle.
If the ricotta is very stiff, you can add a couple of tablespoons of milk, cream, sour cream or yogurt
