Dutch baby in an 8 in skillet: 220 °C against 190 °C, same batter
A Dutch baby is a batter that has to be shocked into climbing. The pan temperature at the moment of the pour decides everything, and an 8 in skillet makes it easy to see.
01Abstract
Identical batter (60 g flour, 120 ml milk, 2 eggs, 3 g salt, 10 g sugar) was poured into an 8 in skillet preheated with 15 g ghee to 220 °C and to 190 °C. The 220 °C version climbed 55 mm up the wall in the first 9 minutes and finished with a hollow centre and crisp edges; the 190 °C version climbed 18 mm and baked into a dense, flat pancake.
02Variables
Independent
- Pan and ghee temperature at the moment of pouring: 220 °C or 190 °C
Held constant
- Batter: 60 g plain flour, 120 ml whole milk, 2 eggs, 3 g salt, 10 g sugar, blended 30 s and rested 15 min
- Pan: 8 in bare cast iron, preheated empty 10 min in a 220 °C oven
- Fat: 15 g ghee added to the hot pan, swirled once, batter poured immediately
- Oven: 220 °C, no door opening for 20 minutes
- Lemon and sugar added only at the table
Hypothesis An 8 in skillet preheated to 220 °C with ghee makes a Dutch baby climb the walls; a cooler pan makes a flat pancake with the same batter.
03Process
- Whisk or blend the batter and let it rest 15 minutes; a rested batter climbs more evenly than one straight from the blender.
- Preheat the empty 8 in skillet in a 220 °C oven for 10 minutes. Add the ghee, swirl, and it should immediately smell nutty but not smoke black.
- Pour the batter in one motion into the centre of the pan and close the door at once.
- Bake 20 minutes without opening. The climb happens between minutes 5 and 12 and any draft during that window collapses it.
- Serve straight from the pan; the fall after it comes out is normal and is not a failure.
04Observations
- 220 °C: the batter climbed 55 mm up the wall by minute 9, the centre hollowed, and the edges were crisp and 2 mm thick.
- 190 °C: the climb stopped at 18 mm, the batter set before it could rise, and the result was a 6 mm dense pancake.
- The ghee at 220 °C smelled nutty at the moment the batter went in and did not burn; at 190 °C it merely melted with no browning smell.
- The 220 °C pancake released from the pan on its own; the 190 °C one gripped the wall where it had set against it.
- Opening the door at minute 7 (a deliberate test on a third batch) collapsed the climb to 25 mm and left a doughy band at the base.
Instrument log
| Pour temperature | Wall climb | Edge | Centre | Release |
|---|---|---|---|---|
| 220 °C | 55 mm | crisp, 2 mm | hollow | self-released |
| 190 °C | 18 mm | soft | dense 6 mm | gripped the wall |
05Conclusion
The pour temperature is the recipe. Ghee at 220 °C in an 8 in skillet produces a 55 mm climb and a crisp shell in 20 minutes; at 190 °C the same batter sets into a pancake. Two rules follow from that: preheat the pan empty rather than with the fat in it, so the fat does not burn while the pan comes up; and keep the oven door shut for the whole 20 minutes, because the climb lives entirely between minutes 5 and 12.
