Preheat the oven to 200 Degrees Celsius.
Add the cake flour, melted butter, eggs, salt and milk to a bowl and whisk until smooth and the consistency of a pancake batter. Add more milk if needed.
Divide the oil into a muffin or Yorkshire pudding pan. 30 ml is enough for 6. 60 ml is enough for +- 12.
Heat for +- 10 minutes.
Pour the batter evenly into the muffin/Yorkie pan. Do not overfill. This batter is enough for 8 - 12 Yorkies.
Bake at 190 Degrees Celsius for +- 25 minutes. Leave in the oven at 160 Degrees Celsius to dry out a bit longer if need be. They should be puffed up and golden. Crispy on the outside, yet soft and tender.
Meanwhile, combine the creme fraiche with herbs, zest and black pepper.
Spoon this mixture into your Yorkshire puds and top with trout ribbons, peas and asparagus. This filling is enough for 6, feel free to double up!
Garnish with extra dill and serve with extra lemon on the side.
When ready to serve, drizzle with lemon-infused extra virgin olive oil. I use Willow Creek, of course.
