Recipe: Peruvian osso buco
Gastón Acurio is without a doubt the most important Peruvian chef of all times. In his Facebook page he promotes Peruvian restaurants back home and overseas and shares recipes with his followers. Like Peruvian mums, he doesn’t use quantities. He might indicate approximates (e.g. “a lot”, “a pinch”), but you have to figure out exact amounts by yourself. This is not hard to do if you have any experience with cooking Peruvian dishes but can become daunting if you don’t.
The first time I made Gastón’s recipe for osso buco I eyeballed the quantities and the result was amazing. I didn’t write the recipe down so I “had to” make it again. The recipe calls for ají panca, which is a dried Peruvian red chilli. You can find it (whole or in paste) in some shops like Fiji Market, Tierras Latinas and online (just Google “buy aji panca”). If you can’t be bothered just use any red chilli paste.
Gastón recommends serving it with pasta. My (low carb) version features cauliflower mash, but you can make it starchier (and more Peruvian) if you serve it with cassava.

I also do not care much for measurements. Add more of what you like, less of what you don’t.

Ooh I haven’t had osso bucco in ages. And love the idea of cauliflower mash. Yum.

By coincidence I’m making osso bucco tonight, and seeing the Fiji Market is a minute from my house, I need some of that chilli paste to give it a Peruvian flavour. Yum!

I think osso bucco’s one of those highly underrated cuts of meat – cooked well, it’s one of the tenderest and most delicious cuts available! I know I definitely don’t cook with it enough myself.
