Steps

1. 1

   In a measuring glass, mix together the olive oil and vegetable oil. In a small bowl, whisk together the egg yolk and garlic. Gradually add 1 teaspoon of water while whisking continuously. Slowly drizzle in the oils, starting with a few drops at a time to emulsify the mixture properly. Keep whisking until the oil is fully incorporated and the aioli has a thick consistency. Add lemon juice and season with salt to taste.

2. 2

   Begin by preheating the oven to 300°F. Cut the squash in half lengthwise and remove the seeds (peel if using butternut squash). Proceed to slice the squash crosswise into pieces that are 1/4" thick. Toss the sliced squash with 2 tablespoons of oil on a baking sheet lined with parchment paper, ensuring they are arranged in a single layer. Bake in the preheated oven until tender, taking care not to allow them to brown, for about 18-20 minutes. Once done, take the baking sheet out of the oven while keeping it turned on for further use.

3. 3

   In a small bowl, mix saffron with 1 tablespoon of hot water and allow it to steep for 1 minute. Then, vigorously whisk together the saffron mixture, eggs, and tarragon in a large bowl until well combined.
