At 9 cents an ounce, the broth here is a bought concentrate: a seasoned tonkotsu base, tare already in it, diluted one part to six to ten parts water. A house tonkotsu starts from pork bones that cost less per finished ounce, but it boils 12 to 18 hours (4 to 6 in a pressure cooker), and that time is gas, a burner nobody else can use, a cook skimming and topping up water, plus a tare and an aroma oil of its own. Even if house broth came in at half this page's price, it would save 54 cents a bowl, about $32 across a 60-bowl day, which is less than a few hours of kitchen pay. Shops that make their own broth do it for the flavor, not the food cost.
The chashu is the biggest line, and the only one portioned by hand. The broth goes out by the ladle and the noodles come in pre-weighed bags, but the pork is sliced off the roll during service, and on a $16 bowl every extra ounce of it adds 2.5 points of food cost. A scale at the slicing station does more for this bowl than any price negotiation.
The add-ons are where a ramen shop makes its margin. An extra ajitama costs 35 cents, and at $2-3 it runs 12-18% food cost, under the bowl's 23.9%. Kaedama, the noodle refill, is often priced at $1.50-2.50; a full 5 oz refill is 90 cents of noodles, or 36-60%, but it needs no new broth, bowl, or seat. Extra chashu sold by the slice works when the slices are counted: two slices of about an ounce each cost 80 cents, so $4 runs 20%, while a full 3 oz portion for $3 runs 40%.
