Mary is celebrating the best produce from our green and pleasant land in another episode full of delicious recipes.

First on the menu is pistou linguini, a pasta dish based on the French sauce, which is a pesto without the pine nuts or Parmesan.

Next, Mary travels to the fields of Hampshire where watercress has been grown for centuries.

After making watercress soup, she takes a ride on the beautiful Watercress Line heritage railway, which once transported the crop to London.
