Best Dumpling Filling Staples — Buying Guide

Fresh ground pork, 80/20 fat ratio — from your butcher or Asian grocery

Pre-packaged supermarket pork is often ground too fine and too lean. Ask a butcher for a coarser grind (3–4 mm) at 20% fat. The fat renders during cooking and creates the soup-like interior Shanghainese xiaolongbao are known for. Leaner pork produces a mealy, dry filling regardless of how much soy sauce you add.

Trade-off: Fresh ground doesn't ship. Buy day-of or freeze raw filling (max 3 months). If your local butcher won't custom-grind, Weee! carries ground pork with higher fat content than standard supermarket packs.

Fresh napa cabbage — whole head, inner leaves only

Napa is not optional for classic pork-and-cabbage jiaozi. It provides moisture and a mild sweetness that balances the pork fat. Critical prep step: salt the shredded cabbage (1 tsp per 200 g), wait 10 minutes, squeeze out the liquid hard. Skipping this step puts too much water in the filling and wrappers split during cooking.

Trade-off: Napa is perishable and bulky — buy the day you wrap. The outer leaves are bitter and fibrous; use inner pale-yellow leaves only. Green cabbage is a hard substitution — much less water content, coarser texture.

Dried shiitake — donko (冬菇) grade, 100–200 g bag

Dried shiitake in the filling adds concentrated umami that fresh mushrooms can't match — the drying process intensifies the glutamates. Rehydrate in cold water for 2–4 hours (cold water extracts more flavour than hot), then squeeze dry and mince. Don't discard the soaking water — add it to your braising liquid or dipping sauce base.

What to look for: Donko-grade has thick caps and a cracked surface from slow drying. Thin, uniform-coloured caps are lower grade. Underside should be cream or pale yellow — grey or dark brown indicates age or poor storage.

Trade-off: Supermarket "dried mushrooms" are often a mixed bag. Asian grocery dried shiitake is reliably better for about the same price. Skip the pre-sliced variety — you need whole caps to control the mince size.

Fresh garlic chives — flat-leafed, not round chives

Garlic chives (jiucai) are a staple in northern Chinese pork-and-chive dumplings (韭菜猪肉饺). The flat, wide leaf has a pronounced garlic-onion flavour that regular chives (round, European) do not replicate. Mince finely and add raw to the filling — they cook through in the wrapper.

Substitutes: If you can't find garlic chives locally, the closest substitute is equal parts green onion (scallion) and a small amount of minced garlic. Not identical, but workable.

Trade-off: Garlic chives are perishable (2–3 days refrigerated) and not stocked at most European supermarkets. Asian grocery stores reliably carry them; Weee! ships fresh. The chive flavour fades fast after cutting — prep immediately before filling.

Lap cheong — standard or liver variety, vacuum-packed, 300–500 g

Chinese sausage adds a distinctive sweet-savoury punch to vegetable-forward dumpling fillings (cabbage + lap cheong is a classic pair). Dice into small cubes rather than mince — the fat pockets hold shape and burst in the mouth. Works especially well in steamed bao-style dumplings where the fat distributes through the dough during cooking.

Varieties: Standard (lean-fat pork) is the default. Liver lap cheong (with duck liver) has a richer, slightly bitter note — use less of it. Both work in fillings; avoid the "Chinese sausage" sold in Western supermarkets which is a different product entirely (more like chorizo).

Trade-off: Lap cheong is very sweet — pair with something sharp (garlic chives, white pepper) or it dominates the filling. Vacuum-packed keeps for months; once opened, refrigerate and use within 2 weeks.
