Congee / Jook (Water to Rice Ratio)

1 part by volume (e.g. 1 cup / 200 g)

Long-grain or medium-grain white rice (or broken jasmine) — Pre-soaking 30–60 min and/or freezing overnight breaks cell walls, producing creamier jook faster

1 part by volume, in place of whole grain

Broken rice or day-old cooked rice — More exposed starch surface area dissolves faster than whole grain — achieves thick-congee texture in roughly half the time, and trends toward the lower (thicker) end of the ratio range; Cantonese dim sum congees often blend 10–20% broken rice into whole grain for a mix of body and rapid dissolution

10 parts by volume (e.g. 10 cups / 2.4 L)

Water or mild chicken or pork stock — Stock contributes body and umami; plain water gives a neutral base for toppings

½ tsp per cup of dry rice

Salt — Added to the cooking liquid from the start

3–4 slices per batch

Ginger (optional) — Simmered in the liquid; removed before serving; classic for stomach-settling congee

Rinse rice until water runs clear. For faster breakdown, soak 30 minutes in cold water, then drain. For the Cantonese technique, toss drained rice with 1 tsp neutral oil and a pinch of salt; freeze 1 hour (optional but dramatically speeds dissolution). Combine rice and cold liquid in a large heavy pot. Bring to a boil over high heat, stirring to prevent sticking. Reduce to a gentle simmer and cook uncovered or partially covered, stirring every 5–10 minutes to prevent scorching on the bottom, until grains have dissolved and the porridge coats a spoon — 45–75 minutes depending on grain and target ratio. For 12:1 (very thin), cook only until grains burst, about 30–40 minutes. Season, then serve in bowls, topped with century egg, ginger julienne, crispy shallots, scallions, or white pepper.

• Freezing soaked rice overnight ruptures cell walls; this single step cuts cook time by 20–30 minutes and produces noticeably silkier jook without a pressure cooker.
• Stirring frequently in the first 20 minutes prevents a thick layer from scorching on the pot bottom — especially important on gas burners with hot spots.
• A pressure cooker reduces cook time to 20–25 minutes at high pressure; use a 9:1 ratio and natural release to prevent the porridge from spattering the vent.
• Use a wide, heavy-bottomed pot — surface area aids evaporation and the heavy base prevents scorching; a thin-bottomed pot will burn the bottom within 10 minutes of simmering.
• Season conservatively at the start; the porridge concentrates as it cooks. Taste and adjust just before serving.
• For restaurant-style smooth texture, blend 20% of the finished congee with an immersion blender and stir back in.
• If congee thickens too much on standing, thin with boiling water — never cold, which seizes the starch and turns the texture gluey.
• A parmesan rind or a few extra slices of ginger simmered in the liquid contributes umami without altering the fundamental ratio.

• Japanese okayu (5:1–7:1)

  Thicker, less broken-down grain; served as a sick-day food or traditional breakfast with umeboshi and pickles; often cooked in a donabe

• Korean juk (6:1–7:1)

  Often made with glutinous rice for extra stickiness; varieties include pumpkin juk (hobakjuk) and pine nut juk (jatjuk); not always savory

• Filipino lugaw / arroz caldo (7:1–8:1)

  Enriched with chicken, ginger, garfish sauce, and kasubha (safflower); topped with hard-boiled egg, chicharrón, and calamansi

• Thai khao tom (8:1–10:1)

  Brothier than Cantonese jook; jasmine rice holds together more; served with ground pork, fried garlic, and a soft egg

• Congee from leftover cooked rice (3:1–4:1)

  Pre-gelatinised starch dissolves much faster; cook 20–30 minutes; use for quick weeknight porridge

• Century egg and pork congee (pei daan sau yuk juk)

  Cantonese classic at 10:1; century egg added in the last 10 minutes; marinated ground pork stirred in raw just before serving

• Broken-rice shortcut (8:1, ~25 minutes)

  Dry broken rice (not pre-cooked) dissolves rapidly at the thick end of the ratio range, reaching congee texture in under half the usual time

• Instant Pot / pressure method (10:1, 30 minutes)

  High pressure 30 minutes with a 15-minute natural release; a looser variant of the stovetop 9:1 pressure-cooker tip above, tuned for electric pressure cookers

• Rice to Water (White Varieties)

  Absorption cooking at 1:1.5 — the opposite extreme of hydration from congee

• Oatmeal / Porridge Ratio

  Similar prolonged hydration logic; rolled oats typically 1:2–1:3 for soft porridge

• Polenta Water to Cornmeal (4:1)

  Another prolonged-cook porridge; coarser starch requires less water for equivalent body
