A Carinderia Chalkboard Menu: Cook the Fast-Moving Ulam Before the Slow Sellers

A carinderia chalkboard promises dinuguan, ginisang gulay, adobo, fried fish and more. The temptation is to cook everything early so the display looks abundant. But the slowest-selling pan can become expensive waste by lunchtime, while the most popular dish disappears before the queue ends. Better planning starts with actual sales, by hour and dish, then uses a small first batch plus a realistic second-batch decision.

Record the sold portions, not impressions of the queue

For several comparable days, record each dish’s opening portions, sales by time, staff meals, unfilled requests and stock left at closing. A dish that sold six portions because only six were prepared cannot be judged less popular than one that sold eighteen. Note when it sold out. Separate a genuine zero-demand period from a period when customers could no longer buy it. Tuesday and Saturday may need different records; a three-day pilot is a starting observation, not a reliable forecast of every future week.

Rank dishes by contribution and demand

Use per-plate costing to separate the selling price from costs that change with the number of portions sold. In a fictional comparison, eighteen plates each contribute ₱24 after the stated per-sale costs, giving ₱432 toward batch and fixed costs. Six plates of another dish contribute ₱35 each, giving ₱210. Then deduct any production costs, waste or overhead not already included. Do not charge the same ingredient twice. Supplier invoices set the cost; DA prices are only a wider reference. Source 1

Schedule the second pot without gambling on food safety

For chicken adobo or another slower dish, measure a complete first batch and decide in advance when a second batch could finish. Reserve raw ingredients under refrigeration, not as half-cooked meat waiting on an idle burner. A refill needs its own cooking and holding record. Keep finished hot food at least 60°C and use a fresh serving vessel instead of mixing new food into an old pan whose history is becoming unclear. If there is no safe burner or holding space, reduce the menu. Source 2

Use the chalkboard as a promise, not an aspiration

Make the board distinguish “available now” from a later batch that has a credible finish time. Erase a sold-out dish promptly and record customers who asked for it after it ran out. A small regional special can still earn its place even if another dish sells faster; give it a deliberate trial quantity and compare results. At closing, count unsold food, protected usable ingredients and requests that the kitchen could not fulfil. Those are three different signals for tomorrow.

Use sales and stockout records together

1. Record prepared, sold and unsold portions by dish over several comparable days.
2. Calculate direct contribution per plate rather than relying on popularity alone.
3. Assign first-batch quantities to reliable sellers and small trials to specials.
4. Only promise a second batch if there is safe storage, burner time and actual demand.
5. Update the menu board honestly and reconcile waste at closing.

Fictional two-dish sales comparison

• Chicken adobo — Plates × contribution: 18 × ₱24; Daily contribution: ₱432.
• Vegetable special — Plates × contribution: 6 × ₱35; Daily contribution: ₱210.
• Combined — Plates × contribution: 24 plates; Daily contribution: ₱642 before overhead.
• Unsold trays — Plates × contribution: Record separately; Daily contribution: May erase the apparent surplus.

Fictional prices, margin and demand; use actual daily production data to decide.

Change one production decision at a time

Increase the first batch, move a second batch earlier or simplify a slow-selling dish only after checking what the record actually shows. Keep the portion and selling price consistent during a small trial so the result is interpretable. A chalkboard works best when it describes food the kitchen can reliably produce and serve.
