Best Stainless Steel Pot for Pap — Why "Sandwich-Bottom" Is Non-Negotiable
Best Stainless Steel Pot for Pap — Why “Sandwich-Bottom” Is Non-Negotiable
TL;DR
If you've decided on stainless steel for pap, only buy sandwich-bottom (encapsulated-base) SS. Single-ply SS pots burn pap at the centre. Our top pick: Capsule Sandwich Bottom Stockpot 30cm/20L (R899). For a complete kitchen: Bon Voyage S27 27pc Set (R1,399).
Why Single-Ply SS Burns Pap
Stainless steel conducts heat ~12× worse than aluminium. Direct flame creates a 4–6cm hot ring under the burner, while the rest of the base stays cooler. As pap thickens and stops convecting, the hot ring scorches the bottom layer instantly.
What “Sandwich-Bottom” Solves
A bonded aluminium or copper disc — typically 2–4mm thick — is fused between two SS layers in the base. Heat spreads sideways across the full base, then transfers evenly. Pap cooks like it would on aluminium, but with SS benefits (no acid reactivity, dishwasher-safe, induction-ready).

Verifying Sandwich-Bottom Yourself
Look at the base from the side. A sandwich-bottom pot has a visibly thicker base (often a different colour band where the aluminium core shows through the seam). Single-ply SS has a uniformly thin wall continuing into the base.
Frequently Asked Questions
Why is sandwich-bottom stainless steel essential for pap?
Stainless steel conducts heat ~12× worse than aluminium. On a direct flame, single-ply SS creates a 4-6 cm hot ring under the burner while the rest of the base stays cooler — perfect conditions for scorching pap. A bonded aluminium core in the base of sandwich-bottom SS spreads heat across the entire base, eliminating hot spots.
How do I tell if my stainless steel pot is sandwich-bottom?
Look at the base from the side. A sandwich-bottom pot has a visibly thicker base, often with a different colour band where the aluminium core shows through the seam. Single-ply SS has a uniformly thin wall continuing into the base. Cheap SS pots from generic retailers are almost always single-ply.
Can the Bon Voyage S27 27pc set cook pap?
Yes. The S27 has a fully encapsulated thick core base — sandwich-bottom construction. The 24cm casserole or larger pots in the set work well for pap. Induction compatible.
What size stainless steel pot do I need for 50 people of pap?
A 35 L stockpot (Capsule Sandwich Bottom 35cm, R 1,099). For larger events, the 40 L pot (50-people capacity) is R 1,299.
Will any stainless steel cookware work on induction?
Only if it has a magnetic base. Most sandwich-bottom SS is induction-compatible because the encapsulated base is magnetic. Single-ply SS may or may not be — always check the base for the induction symbol.
Is stainless steel better than aluminium for pap?
For an induction household, yes. For gas or electric coil, heavy aluminium (Sapphire S7 or NW range) outperforms stainless steel on price and heat behaviour. Most SA cooks who switched from aluminium to SS did so because they got an induction stove, not because pap cooks better in SS.
