I happen to have a bonafide apple tree in my SoCA yard, quite unusual for this area. I do nothing to care for it, but it rewards me with a plethora of apples (rather like Golden Delicious) this time each year. I borrowed my friend's antique cone shaped Chinois colander to make applesauce. You cook the apples, skin & all, until they’re soft enough to push through this sieve with a wooden mallet (rather like a rolling pin with a pointed end.) I've found they're still available but very expensive. I'm now searching E Bay for a vintage model. You could always peel & core the apples & proceed to make applesauce in the traditional way; or try pushing them unpeeled & cooked through a regular colander. In any case, here’s the resulting home grown apple sauce made better-butter. I thought it to be a “breakfast” item, but I took some along to a dinner party where biscuits were served and came home with an empty jar! Maybe it’s due to the secret ingredient?
