Porto has port, Lisbon has ginjinha and, as I discovered on a recent trip to Evora, the Alentejo region has a liqueur little known outside of Portugal called poejo. Poejo (the Portuguese name for pennyroyal) is a slightly minty sweet liqueur made from the herb pennyroyal. It is served at the end of a meal, as it is said to be a good digestive. While the flavour reminds me of a sweet minty mouthwash, that’s not a criticism, as, when served with ice it is very refreshing, especially after a heavy meal on a hot day – perfect for those Alentejo summer nights! However, it is best drunk in small quantities, as it is made from a base spirit to which pennyroyal, water and sugar are added, resulting in a fairly high alcohol content of around 20%!
