"Forkish" Yeast Spoons

<p>Ken Forkish, a Portland, OR baker of much renown, &nbsp;wrote two of my favorite books on baking;<i> "Flour, Water, Salt Yeast", and “The Elements of Pizza”.&nbsp;</i> They changed the way I bake. &nbsp;There is one annoying problem with both books: The recipes make 2 large loaves of bread, or 5 pizzas. &nbsp;In my opinion, his best recipes use a pre-ferment called “biga”. &nbsp;If you scale the biga pizza dough recipe down to a single pizza, it calls for 0.07 grams of instant yeast. &nbsp;While kitchen scales with 0.01g resolution are available, measuring such a small quantity is, at best, tedious.&nbsp;</p><p>The solution is to have measuring spoons calibrated not in tablespoons and teaspoons but in grams of yeast. &nbsp;The spoons here are calibrated for SAF Red Instant Yeast, which is readily available online, at least in the US. &nbsp;It's possible to adjust the OpenSCAD file for other yeasts and for your printer's particular extrusion settings (see below).</p><p>Except for the spoons for 0.32g and smaller these should be printed with supports. &nbsp;The .3mf file included here prints all seven of the spoons for which .stl files are included but lifts the smaller spoons above the build plate on supports so that all of the type begins at the same level (approximately 8.288mm) to enable two-color printing of the entire set at once. &nbsp; Prusa Slicer's variable layer height option should be used at and above the color change point for optimum type clarity. The .3mf file contains both the variable layer height and color change adjustments, but modify them to suit yourself.</p><p>The OpenSCAD customizer can be used to generate the .stl for any arbitrary amount of yeast your favorite recipe requires. It can also generate .stl files for yeast spoons that print without supports, but for the larger amounts the handles become annoyingly thick, and each spoon's type starts at a different height.</p><p><strong>C A L I B R A T I O N:</strong></p><p>The actual measurement of each spoon, especially the smaller ones, is quite dependent on both whether your printer over or under extrudes <i>and</i> on your preferred spoon leveling technique. (Gently tapping the side of the spoon to level it produces measurably different results than using a knife blade or other straight-edge to level the yeast). &nbsp;</p><p>To calibrate your set of spoons print a test copy of the 0.2g yeast spoon. &nbsp;Use it to measure 10 level spoonfuls of your favorite yeast onto a kitchen scale with at least 0.1 gram resoultion. &nbsp;If the measured weight is not 2 grams use the OpenSCAD Customizer to adjust the value of <strong>fudge</strong> to:</p><blockquote><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 2 / measured weight</p></blockquote><p>UPDATES: &nbsp;</p><p>Added a box to hold the spoons. &nbsp;If you generate the .stl from OpenSCAD you can use the customizer to add a name to the box lid.</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p>
