4 pieces of good ostrich fillets (we get our ostrich from Klein Karoo ostrich)
Seasonal vegetables of your choice (at the restaurant we serve different colours of baby beetroot)
1/2 cup white wine
1/4 cup white wine vinegar
1/4 cup sherry vinegar
3 tablespoons sugar
1/4 cup black mustard seeds
1/4 cup yellow mustard seeds
25g corn flour
Biltong dust to taste
Grated gruyère to taste
Mix everything in a non-reactive bowl and let it stand at room temperature for 2 days. When ready, pulse in a blender. The seeds need to be broken but not smooth. It will have a very strong taste at first but the longer it rests the more the flavour will mellow.
Melt the butter in a medium saucepan, add the flour and let it cook on medium heat for 5 minutes. Add the milk while whisking constantly. (You are basically making a béchamel).
At the end add the biltong and cheese.
Be careful with the salt as the cheese and biltong can be salty. But this mixture loves black pepper so don’t be shy.
Let the mixture cool down in the fridge. Once cooled roll into 30g balls.
Dip the balls into flour, then beaten eggs, followed by panko bread crumbs. Deep fry the balls until just golden. About 10 seconds.
Sear the ostrich on high heat for 3 minutes on both sides. Smear the mustard on top and roast for 5 minutes in a hot oven.
Rest the meat for 4 minutes before serving.
