Sometimes I worry I'm going to completely ruin a dish if I add something I'm not 100% sure about. Other times I take the risk.
Last night for example I made a rack of lamb for dinner and seasoned it with a bit of olive oil, salt, rosemary, thyme and herbs d'provence. It was delicious, if I do say so.
Cooking is about taking risks and not being afraid to order a pizza if you ruin whatever you were attempting to cook.
Here's a great tool to help with herbs.
Enjoy your day!
