What kind of oil is better for spraying hot oil?

Hot oil is generally salad oil, but it is not simply hot salad oil. Instead, salad oil is changed into onion oil in advance, then heated and poured on shredded onion when steaming mandarin fish.

Why choose salad oil?

Salad oil refers to high-grade edible vegetable oil made from various crude vegetable oils after degumming, decoloring and degreasing. There are two reasons for the hotel to use salad oil: the first is that salad oil is colorless and tasteless, and will not rob the onion of its fragrance. The finished product is full of onion fragrance, especially suitable for steamed fish, which is slightly different from the onion tofu and onion sea cucumber we usually make. Second, salad oil is cheap, and the salad oil used in hotels only costs 4-5 yuan a catty.
