The Gildas are a typical Basque product that is not easy to find online. But from BarOkela.com you can order your Gildas trays online to take away and brighten up any appetizers. We recommend to keep in the fridge if they are not going to be consumed at the moment and sprinkle with extra virgin olive oil before consumption. They can last for several days if stored in the fridge for up to 3-4 days.
