I've seen a lot of clawfoot tubs with subway tile accent wall(s). Some clawfoot tubs are painted black. Maybe the grey tile floor, white subway tile, black outside the tub? too much tile? too much white?
Lemon yoghurt cake I made this with mandarin and added poppy seeds, be careful not to overbeat or it gets a little too dense when it cools down! Not too sweet and cooked really quickly, good afternoon tea cake or if someone drops in unexpectedly!
