Much to the chagrin of my mother, I made it a point about a decade ago to standardize old family recipes on "from scratch" versions. As part of the process, I also did some research on old recipes and fixed some of the corruption of these recipes that occurred during the copying and recitation, bolstering them with culinary techniques that were in use at the time. I also captured things that drift over time, such as crude protein and carbohydrate measurements and grind sizes in flour. I provided standardized weights and measurements, in MKS units, preferring mass, when possible, over volume.

She's upset that the recipes are different, but when it comes to recipes from the thirties and later based on using a box of this or a can of that, these recipes are resistant to shrinkflation. The downside is that these recipes miss out on the advanced chemistry that went into making these boxed mixes so great to begin with. But, in my opinion, that's a small price to pay for reproducibility.

Some recipes, like cakes and cookies, will need to be adjusted once a generation. For these recipes, I include notes about how to tell when certain ingredients are "off" so that these can be re-calibrated as ingredients change in the future. Ingredients change. Some are no longer available. Others are derived from newer varieties or hybrids that have different flavor profiles. For instance, bananas taste differently than they did sixty years ago. That old and dusty banana pudding recipe meant to reproduce that amazing pudding that your great-grandmother used to make won't taste the same unless you adjust the amount of isoamyl acetate; modern varieties have less of this compound than the old Gros Michel varieties did. You can occasionally find Gros Michel bananas if you want to taste the difference, but they are no longer a viable cash crop due to their susceptibility to Panama disease.
