Sweet and Sour Pork Loin (Pork Loin Glazed with Adrien's Secret Sauce)

'Season the pork loin with salt, black pepper, garlic powder, and vinegar or lemon juice.'

'Let it sit for an hour to absorb flavors before roasting.'

'In a saucepan, combine all ingredients except cornstarch and liquor

Simmer over low heat for 5 minutes.'

'Add two tablespoons of the mixture to the cornstarch, then mix everything together, stirring slowly until thickened.'

'Finally, add the Cointreau and simmer for 10-15 minutes without stopping, stirring constantly.'

'Twenty-five minutes before the glazed pork loin is ready, cover it with one-third of this sauce.'

'Fifteen minutes later, add another one-third.'

'And finally, when it's done, add the remaining sauce.'
