Ingredients

2 -3 cups radish tops, roughly chopped (leaves)
2 -3 garlic cloves, quartered
2 tablespoons olive oil
2 tablespoons lemon juice
1 teaspoon white sugar
3 tablespoons parmesan cheese, grated
2 tablespoons pine nuts
Salt and pepper
Directions

1.  Drop the first four ingredients (leaves, garlic, olive oil, lemon juice) to the bowl of your food processor and pulse to form a thick paste. Add more olive oil if necessary to bring to your desired consistency.

2.  Add the sugar, cheese, nuts, salt and pepper and pulse to combine. Adjust the salt and pepper to taste. If the pesto is still a bit bitter, add 1/2 tsp of sugar and pulse.
3.  Chill to combine flavors and use in your favorite pesto application.
