Hi, Mary K.-I get shredded apricots, pecan meal, mini-lemon chips, mini-cinnamon chips, lemon oil, orange oil, dried cranberries, currants, and so much more from the Baker's Catalogue www.bakerscatalogue.com
Almond meal and pecan meal I get in 5# bags ea. from Country Life Natural Foods in MI...5# almond meal sells for $ 9.75 and 5# pecan meal sells for $ 9.25...the bags are very heavy and freeze well or I re-bag them in freezer ziplocks.
My husband has been a teacher for 38 years and I send goodies such as muffins all the time...the kids beg for more and send me thank-you notes!!
Buttermilk makes muffins and everything else SO much more moist and delicious! Hope this helps you get some great ideas for your own treats!
