I have the same problem….I got a few technical tips from Alton Brown’s Good Eats and they really helped.
1. I use self-rising flour (like Ma Mae Alton Brown’s Grandma) and omit NaCl & rising agents because i noticed a few biscuits would rise and others not or if at all (hence the hockey pucks) . So I figured that I wasn’t able to get my “dry team” incorporated good enough no matter how well I tried. So I switched flour and It has helped a lot!!!! And I do use buttermilk in my “wet team” and there is never that nasty buttermilk taste (like when you try to drink it). It adds flavor and is nice and thick which Seems very important to a good biscuit.
2. Crisco shortening as your fat (the thick white solid grease) makes a fluffier biscuit. But using butter in addition to the Crisco will add flavor (but I didn’t really notice a flavor difference so I stick with all Crisco) Work fast when cutting into flour because you don’t want the fat to get too warm ( harder to get it cut in). Don’t use the butter flavored Crisco…it is way too soft and miserable to work with & my biscuits didn’t rise very well (tried it twice with same results). Some use their finger tips to cut in the fat but my hands are too warm and the fat just kinda sticks more to my fingers so I do use a pastry cutter or a fork.
3. Barely work the dough (like the others said) but when you “roll out” (I use my hands and not a rolling pin) try to get as much yield from it as possible so that you have less dough as possible to reincorporate into another rolling/cutting session. The second will always be less fluffy & not rise as much. Before you start “kneading” when it’s still in the bowl, it will be sticky and a bit of a mess BUT it is supposed to be. So don’t let that make you over mix it (that was one of my problems). It will come together really fast when you work it a little on your board. It may not look perfect like rolling out cookie dough and make you think that you need to work it more BUT don’t. Just work it to the bare minimum.
4. When cutting with your biscuit cutter, press straight down all the way before giving it a twist.
5. Like the others said, place close together on baking sheet to get an even rise (shoulder-to-shoulder)
6. Press the centers down with your finger tips just a little to make an indentation, also for an even rise. Paula’s puts melted butter on tops which is yummy and makes the tops turn golden….if using all Crisco you really need this for the tops to turn golden.
7. Ma Mae said to get them n the oven right away because you want them to only rise in the oven.
I know to all the biscuit maker’s out there this is all rudimentary, a great big DUH
but for those of us who have only “made” biscuits from the Dough Boy…..it’s all new. When i first tried these tips…...I made 5 batches back-to-back in a row to make sure my results were repeatable! And they were!! Once you get it down….whipping up a batch of homemade biscuits takes no time at all. The ingredients are always on hand. So why do we buy the Dough Boy Cylinder’s??? I now ask myself that ll the time
I don’t care what the old saying is IGNORANCE IS NOT BLISS!
Good Luck and I hope my experiences are of a help to you!!!!!
