The Posdol Blog

A Pinch of Salt,
A Dash of Lime.

POSDOL came from this idea: a pinch of salt and a dash of lime are what make all the difference to any dish. Not the protein, not the technique — the small things. This blog is about those small things. The specific version, for people who are actually building something in food.

The 4:2:1:0.5 Ratio — Aloo Palak

A chef at IHM taught me a ratio I have never forgotten. Four parts spinach, two parts coriander, one part mint, half a part green chilli. Not a recipe. A ratio. Which means it works at any scale, any quantity, any day. The aloo palak built on that ratio — with the story behind it.

What this blog covers

Five pillars.
All from the work.

Every post falls into one of these five areas. The writing comes from operator experience, not from reading about it.

01

Recipes

Real recipes. With the memory behind them, the technique that matters, and the ratio worth memorising.

02

Operator Reality

Cloud kitchen economics, menu engineering, vendor management, kitchen systems, P&L. The specific, not the general.

03

Food Science

Applied nutrition, ingredient function, nutrigenomics. What food does in the body, explained by someone who cooks it.

04

Building & Closing

Yellow Door, Seoul Sandwich, what the work taught. The decisions that most founder content skips over.

05

The Long Game

Personal systems, health as operations, the pattern-finding approach to building things. The philosophy behind the work.
