1.Heat oil in a 6-litre (24-cup) pressure cooker; cook veal, in batches, until browned all over. Remove from cooker.
2.Add onion, garlic, anchovy and chopped basil to cooker; cook, stirring, until onion softens. Return veal to cooker with tomatoes and wine; secure lid. Bring cooker to high pressure. Reduce heat to stabilise pressure, if required; cook 30 minutes.
3.Release pressure using the quick release method (see tips); remove lid. Stir in olives; season to taste.
4.Serve veal with sauce, sprinkled with basil leaves.
If you have an electric pressure cooker you won’t need to reduce the heat to stabilise pressure, your cooker will automatically stabilise itself. Always check the manufacturer’s instructions before using. Quick release method: Each time the lid is removed from the cooker, the pressure must be released quickly first. Use tongs (steam can burn your fingers) to turn the pressure valve on top of the cooker to open the valve and release the steam. We use this method when adding ingredients and when checking the food toward the end of cooking time.
