Arizona Cheese Crisp
This is the most Arizonan dish I have written about and the hardest to date: the phrase appears nowhere in the federal publishing archive, and in two state newspaper collections every apparent hit turns out to be crisp bacon.
Begin with the absences, because here they are the finding. A search of the whole of govinfo for "cheese crisp" returns zero documents — against two for the Sonoran hot dog and eleven for the chimichanga. Georgia's historic newspapers return 62 pages, and I read every one of them: each is a burger or a taco listing a "cheddar cheese, crisp bacon" or a "cheese, crisp lettuce", or else a packaged supermarket snack, and not one is this dish. Nebraska's return 11 and the ones I opened are the same thing — a Taco Bell coupon in The Daily Nebraskan running through the autumn of 1988 whose Burrito Supreme holds "real cheddar cheese, crisp lettuce". The California Digital Newspaper Collection, which carried the San Diego fish taco for this site, now answers 403 to every request I make. And the best Tucson restaurant writing I have been able to open, the syndicated column of 20 November 1985 that dated the chimichanga, goes through the city's specialities and does not mention a cheese crisp at all: what it names instead is "magnificent tostadas a.k.a. Mexican pizzas. Each disk is a husky corn tortilla, baked to a fragrant crisp, its broad surface a mottled field of patches that are alternately brittle and soft." That is the right texture described in print, and it is on corn, under a different name. So I cannot give you a year, a city or a first restaurant for the cheese crisp, and I am not going to invent one.
One procedural note, because it is a correction worth having. Arizona's own archive is no longer the CONTENTdm installation that refuses scripts: the Arizona Memory Project now runs on Recollect, and a real browser reaches it without trouble, past the challenge page that stops curl. It holds exactly the material this dish needs — runs of Arizona Days and Ways, Arizona Grocers, a 1950 restaurant menu, a whole item type for city directories. What it does not have is an exact-phrase search. Quotation marks are ignored: "crisp governor" in quotes returns more than ten thousand items, and "cheese crisp" returns 8,135, which is an AND of two common words and no use at all for dating a two-word dish name. The one dated, readable description of the method I could find is in a syndicated newspaper food column by Miriam Rubin, "Appetizers celebrate Cinco de Mayo", reposted in full to the newsgroup alt.food.mexican-cooking on 2 May 2005 — the only message in that entire group archive that contains the phrase. Its recipe is headed "Tostada Grande con Queso (Cheese Crisps)", credited there to Marilyn Tausend's book Cocina de la Familia, and the instruction is the thing worth having: oven at 375, "Place tortillas directly on oven rack and bake until they start to puff up and become crisp, 3 to 4 minutes", then "Pull out oven rack, sprinkle tortillas with cheeses and push oven rack in. Bake until cheese melts, 4 to 5 minutes more", then cut into wedges. Two stages, bare tortilla first, nothing underneath it. Nobody cooks for this site and this dish has no public-domain ancestor; the quantities below were worked out for this page from that dated method and from the federal cheese standards.
Why this version works
The tortilla is crisped empty first, and the order is not optional. Put cheese on a raw tortilla and the cheese melts in three minutes while the bread underneath is still a bread, because the melting cheese seals the top surface and the water in the dough has nowhere to go. A flour tortilla is 31.8 percent water by USDA's measurement; that water has to leave before the cheese arrives. Hence the two stages in the 2005 column: three or four minutes naked at 375 until it puffs and goes brittle, then the cheese, then four or five more. And it goes on the bare rack rather than a tray, so heat reaches both faces at once and the underside dries instead of steaming against metal — which is also why the result blisters in patches rather than browning evenly.
There is no binder, no pan and no second side, so nothing on it may be wet. Every other melted-cheese dish has somewhere to hide water: a quesadilla has a second tortilla over the top, nachos have depth, an enchilada has sauce. A cheese crisp is a single open sheet, and any liquid put on it lands on crust it has just taken ten minutes to make. Roasted green chile goes on patted dry between paper, chopped small. Fresh tomato, raw onion and sour cream belong on the plate beside it or nowhere. If you want chorizo, cook it, drain it hard and crumble it fine, and put it under the cheese rather than over, so the cheese seals it away from the tortilla.
The federal labeling book has no name for this dish, and the reason is instructive. The Food Safety and Inspection Service names meat and poultry products, so its Food Standards and Labeling Policy Book carries entries for "BURRITOS", "CHIMICHANGA", "ENCHILADA", "ENCHILADA - Sonora Style", "TORTILLA WITH MEAT" and "TOSTADA WITH MEAT", with ten mentions of taco and two of nacho — and not one occurrence of cheese crisp or quesadilla in the whole book. A tortilla with nothing on it but cheese falls outside the agency's jurisdiction entirely. The consequence is a small oddity: the only definition of the word tortilla anywhere in that book is a corn one, "a thin, flat unleavened masa cake which is baked on both sides", while the thing Arizona crisps is wheat and twelve inches across. This dish has no federal identity, no trademark anybody has enforced and no printed birthday. It has a method, which is above, and a state.
Monterey Jack is allowed to be wetter than cheddar at exactly the same fat, and that is the whole reason it flows. The two standards of identity are worth reading side by side. Monterey cheese, at 21 CFR 133.153, has a minimum milkfat of "50 percent by weight of the solids" and "the maximum moisture content is 44 percent by weight". Cheddar, at 21 CFR 133.113, has the identical 50 percent fat floor and a maximum moisture of 39 percent. Same richness by law, five percentage points less water. The measured products follow: USDA records cheddar at 36.6 grams of water per hundred against Monterey at 41. On an open tortilla with no sauce, no roux and no pan to hold it, that difference decides everything — the wetter cheese flows and stays a sheet, while the drier one tightens and weeps oil. The procedures in the two standards differ in the same direction: cheddar's requires the curd to be cut into slabs "so piled and handled as to promote the drainage of whey and the development of acidity", and Monterey's has no such step, the drained curd going straight into a cloth or a hoop to be pressed.
