Failed scones

I made scones this morning but it didn't go that well; I forgot the oven timing for them and had them in 20 instead of 15 minutes, I used too much salt, I think because the butter was salted too and the bicarbonate I used instead of baking-powder and that I made half a batch which made the proportions all wrong, it was only half ok anyway but still eatable, at least to me.
