Potato, Leek And Pecorino Soup
This is such a tasty and easy way to have a great warming mug of goodness in your hands on a wintery day. Could be lunch. Could be dinner. Add bread!
Soup is probably my favourite thing to make in the Thermomix. We always were a big soup family, but now it is the most requested weekend lunch item! I really can never go back to canned soup. Tried and failed! There is something about putting in a few ingredients, adding liquid and finding out you have the most amazing, fragrant, steaming and delicious hot soup at the end of it all; why would you ever not want a Thermomix? Really!
Parmesan and pecorino are both hard, aged Italian cheeses, but they differ in flavour, texture, and origin. Parmesan—specifically Parmigiano Reggiano—is made from cow’s milk and aged for at least 12 months, resulting in a nutty, savoury flavour with a firm, granular texture. Pecorino, on the other hand, is made from sheep’s milk (the name comes from pecora, meaning sheep in Italian) and tends to be sharper, saltier, and more pungent, with a slightly oilier mouthfeel. Pecorino Romano is the most well-known variety, often used in traditional Roman pasta dishes like cacio e pepe or amatriciana. While parmesan offers a more mellow, buttery depth, pecorino adds a bold, briny punch—both are delicious, but knowing the difference can elevate your cooking.
