Personally, I think if you just use extra-virgin it's quite strong and it can overpower some of the fragrance and the nuttiness of the pesto, but it's up to you.
The sesame wok oil is gonna add a really lovely nuttiness to the roast potatoes, but also because this oil has a really high burning temperature, it's gonna make them really crispy and delicious.
The black pepper comes through, the Parmesan adds like a salty nuttiness but it also helps thicken the sauce and I love the Meyer lemons in this but regular lemons will totally work, bye guys!
