No, it's not at an end, just the focus will change! You'll eat a lot more brownies and tea bread than airy fairy Victoria sponge!
Muffins work well, and using ground almonds makes for heavenly (and v v wicked) brownies.
Darina Allen's (Ballymaloe Cookery School) Healthy Gluten Free Eating has some good recipes, including a fantastic banana loaf which doubles up as a muffin batter. I've fed it to non coeliacs without them realising!
Re bread, I've never made my own other than from packet mixes, but like CMOTdibbler, I have gone from bread being my lunchtime staple to rice, or potatoes. Commercial gf bread has come on leaps and bounds, even since my dx 8 years ago, but still not great. Genius is good, esp the seeded one, but I think it's always better toasted!
And as an aside, Salute pasta found in Waitrose is the best I've come across, and Nature's Path Mesa Sunrise breakfast cereal (known here as sunshine flakes and loved by my kids) Is fab, if a little bit expensive! so they only ever get some as q treat!
It does get easier. After dx, my usual shop took three times as long whilst I scrutinized labels. Now I cook much more from scratch, and know which things I can and can't buy the non gf alternatives.
Good Luck!
Oh, and Honeybuns cakes, found in Waitrose cafe, are to die for!
