Adapting Medieval Recipes For Your Kitchen
Most people who pick up a medieval cookbook hit the same wall within the first three recipes. You have an ingredient list that includes things like "verjuice," "grains of paradise," and "sugar of candie," and you're suddenly very aware that your local supermarket doesn't stock them. The original Feast Book attributed to Richard II's household has been around since the late 1300s. It records the actual meals served at court, which means the recipes are technically accurate to the period but completely impractical for someone cooking in a modern kitchen with standard equipment. This adaptation takes those original manuscripts and translates them into something a home cook can actually execute. The core principle is substitution without losing structural integrity. When the original calls for verjuice, which is the sour juice of unripe grapes or crabapples, you use white wine vinegar diluted with water at a two-to-one ratio. When it calls for "sugar of candie" (candied sugar crystals used as both sweetener and thickener), you swap in finely granulated sugar dissolved in a small amount of hot water before adding it to the dish. I learned this through making the original recipes fail repeatedly. My first attempt at the peacock recipe from the feasts produced a bird that tasted like bitter vinegar and stale bread because I didn't account for the fact that sugar of candie functions as a stabilizer, not just a sweetener. Adding regular sugar at the same point caused the sauce to break and separate entirely. The fix was to prepare a small slurry of sugar and water separately, then temper it into the hot sauce while whisking constantly. That technique alone saved roughly half the dishes that would have otherwise been wasted.
The resource itself covers about eighty recipes adapted from the originals. Each one gets a modern ingredient list, a contemporary cooking method, and notes on where the original technique diverged from what works today. The adaptations tend to favor oven-roasting over open-fire spits because most home cooks don't have access to rotisserie setups. Where that matters, like for the whole roast venison, the book provides instructions for using a Dutch oven with a trussing rack as a reasonable stand-in. One thing the adaptation gets right that other versions don't is the spicing ratios. Medieval cooking heavily favored combinations of cinnamon, ginger, cloves, and long pepper that seem overwhelming at first glance. The original manuscripts use volumes that would make most modern palates recoil. The adapted recipes dial these back to something closer to what people actually enjoy today while preserving the character of the flavor profile. A recipe for frumenty with peacock might use half the cinnamon and a quarter of the pepper compared to the manuscript, but it still tastes like what a medieval guest would recognize as that dish. There are real limitations here though. Some of the techniques simply cannot be replicated outside of a proper hearth or spit setup, no matter how hard you try. The texture of meat cooked over an open flame with intermittent basting in its own rendered fat is fundamentally different from anything you get in a conventional oven. The adaptation gets you close, maybe eighty-five to ninety percent of the way there depending on the cut of meat and your equipment. If you're chasing authentic texture for something like a whole swan or capon, you're going to need either an outdoor smoker or an exceptionally good reverse-sear method with a wood chip addition in the final twenty minutes.
The resource is available as a free digital download from several recipe archive sites that host public domain historical cooking texts. I found the version hosted on Medieval Cookery dot com to be the cleanest PDF available, though the formatting can be a bit cramped on smaller screens. Some of the ingredient substitutions aren't listed directly in the recipes, so you need to skim the introductory material first to understand the substitution framework before you start cooking through the recipe list. Without that context, you'll end up confused about why a recipe for saffron pottage tells you to add "substitute for grains of paradise" without explaining what that substitute is. Another practical note: the original recipes assume a household staff of six to ten people minimum. The scaled-down versions in the adaptation are generally generous for two or three people, which works fine for dinner but leaves you with leftovers for lunch the next day on most recipes. If you're cooking solo, plan on either freezing portions or accepting that you'll eat some of these dishes multiple times over. The recipes that tend to work best for beginners are the pottages and papyones. These are thick stews and sauces that forgive minor variations in technique. The more delicate dishes, like the blancmanger variations or the fish preparations involving almond milk, require closer attention to temperature control. Almond milk separates at a lower temperature than dairy, so you need to keep those pans on medium-low heat and stir constantly once the almonds are incorporated. That's one area where the original technique actually had an advantage: the open fire allowed for quicker heat adjustments that a modern stove burner can't always match unless you have good range control.
