An army marches on its stomach - and the reverence for food and wine in the Alentejo helps explain why the Portuguese, with a few exceptions, held on to their corner of Europe for so long.
Locals eschew fast food outlets for old-fashioned diners serving peasant fare, where often humble ingredients are raised to great heights through slow cooking and subtle use of herbs and spices. It's a cuisine which takes what's locally available - pork, chicken, bread, eggs - and adds ingredients introduced by Arabs or Jews or brought home by traders in the days of empire. Coriander, oregano, pennyroyal, cinnamon and wine play important roles in lifting peasant fare into something special.
"Coriander, garlic and bread are the basis of Alentejo food," says Joao Ferriera, a foodie who took us to dinner in an unpretentious tasca in Borba. "Add tomato and you have a meal."
Meat (served in generous portions) is important but Portuguese cooks know how to make a little go along way. My first meal, Migas Alentejanas, didn't sound too flash: a pile of pork bones and crumbly fried sausage on a stuffing of bread. But the herbs in the bread countered the meatiness and it was certainly nourishing.
