Excellent! Thank you for sharing a typical Dutch recipe, seeing it's your grandmother's recipe that's authentic enough for me! Love the grandma recipes and we loved this one. Made as posted and have made it a number of times - and yes have played with the cheeses. Gouda is REALLY expensive here in 'small town Saskatchewan'! This comes together to make for one terrific potato dish. It's so good just mashed that I have done that as well. Thank you for sharing your family recipe - it''s a keeper.
