An old thread maybe, but for those planing their first Camino , one of the first questions asked.
So we are talking LOW budget. I take a detachable 'Camping Gaz' stove and purchase a canister at the first city or big town - it self seals and the stove and gas can be stored separately. I also take a tin mug and billy can which can both be attached to the outside of the pack. So to start , coffee or tea anywhere , anytime.
A boxed litre of Vino -€1.50 or less , A tin of Lentils , cothido , or beans with meat - up to €2.00. Pasta with tomato sauce - max €2. Fruit and fresh veg I find expensive - tinned peaches or corn make a good lunch. Bottled Pimentos(shredded is half the price) on bread , perfect. Bread does not last for much more than a day. Some small shops will sell you single eggs ,or a half loaf of bread.
Meat and cheese are expensive as they are in most parts of the world. What I did learn was that the darker the cheese wax is , the more expensive starting from yellow to black. Morcilla , a blood rice pudding is inexpensive but one needs to get ones head around it - I personally love Morcilla.
So, YES , it is possible to cook ones own food and live off €5 to €7 even WITH a couple of glasses of wine. Remember , my recommendation is for the whole day and not just a single Pilgrim's menu?
Finally , always carry a spare dry ration meal with you , and some snacks - raisins , nuts ...... the Spanish calendar boasts many public holidays when shops are closed - I do hope this helps some of you asparating souls.
