To make walnut pesto (this recipe is from Ritu Dalmiau2019s Italian Khana).
Put 150gm basil leaves, 2 cloves peeled garlic and 50 gm walnuts in a food processor and process till you get a smooth paste.With the processor running, add about 25 ml olive oil in a slow and steady stream.
Stop the machine and add 75 gm freshly grated parmesan and process till the cheese is absorbed. Slowly add another 25 ml of olive oil and process till the pesto is creamy. Season with salt and pepper.
To make the bread : Mix all the ingredients for the dough together. Use a bit more (be judicious) flour if the dough looks very wet. The dough should be moist but should not stick to your hands. Put the dough in a container and cover with plastic wrap or lid, but not tightly. Allow dough to rise for about 2 hours.
After 2 hours of rising, put dough into the refrigerator to chill for at least 3 hours for easy handling. The dough can be kept refrigerated for up to a week. I refrigerated my dough overnight and baked the bread next morning.
When ready to bake, take the dough out and shape the dough into an oval. Lightly dust your work surface with flour and roll the dough out into a rough rectangle about 1/4u201d thick.
Spread the pesto on the rectangle leaving a margin on the sides. Go a bit easy on the pesto or it can be over powering! Sprinkle the pesto nuts evenly over this and then the parmesan cheese.
Fold the sides of the rectangle inwards a bit and then roll the dough with the filling, in jelly roll style. Pinch the dough to make sure it has sealed well.
Now carefully, cut the rolled bread dough into 2 equal halves, lengthwise, with a sharp knife. Twist both halves together like a rope, ensuring the filled sides show on the outside. Place the twisted dough in a greased loaf tin and let it rise for about 1 1/2 hours.
Bake the bread at 180C (350F) for about 30 to 35 minutes till done. Unmould and cool on a rack. Wait till the bread has cooled completely before slicing.
