The recipe for a perfect Yorkshire Pudding (the scientific way)

When is a Yorkshire pudding not a Yorkshire pudding? Yorkshirefolk would say when it’s not made in Yorkshire. But according to one scientist it is when it’s less than 4 inches tall. That’s about 10.24 cm. But somehow Yorkshire puddings don’t seem right metric so let’s stick to a good old-fashioned 4 inches despite this definition coming a good old metric organisation The Royal Society of Chemistry.

According to the RSC:

“The judgement followed an enquiry from an Englishman living in the Rockies in the USA who emailed the RSC seeking scientific advice on the chemistry of the dish following a string of kitchen flops.

Ian Lyness had contacted the RSC to get an explanation for why his attempts at cooking traditional Yorkshire puddings in Colorado had gone flat.

In other parts of the USA Mr Lyness had successfully produced puffy, towering puddings but in the high country he had low results.

The RSC is now checking with fellow scientists to see if cooking the famed dish in a mountain climate would lead to pressure problems.”

Chemical scientist and author John Emsley, of Yorkshire, claimed that people not from that county rarely produced worthy Yorkshire puddings.

“It’s in the blood and instinct of people born and raised there,” said Dr Emsley.

“You can always tell from the look and taste if the cook has the right touch and it is almost pitiful to observe the stuff that comes from some southern ovens – flat, pale and soggy much of the time.”

Former Cambridge academic Dr Emsley added: “I have seen many grim results from people who have tried to get their Yorkshires to rise. They frequently made gross errors. After all, cooking is chemistry in the kitchen and one has to have the correct formula, equipment and procedures. To translate the ingredients into chemical terms, these are carbohydrate + H2O + protein + NaCl + lipids.”

Some amateurs even place the batter in the fridge first. What kind of foolish act is that?

The RSC invited Dr Emsley to define Yorkshire pudding, by delving into the lore of his home county to produce the definitive recipe.

“It is wonderful as a starter and main course, as we all know,” he said. “However, we have lost sight of it as a superb dessert to follow the main meal and we should aspire to bring it back again as a genuine pudding after many years absence.”

Next year the RSC will, as one of the lighter parts of its food campaigning, produce a leaflet on the way to make the ideal 10cm Yorkshire pudding and will push for its renaissance as a dessert.

So here we go, The Royal Society of Chemistry Yorkshire Pudding Recipe:

Ingredients

Tablespoon and a half of plain flour

1 egg

Half milk, half water to make a thin batter

Half a teaspoon of salt.

Method

Put flour in a bowl, make a well in the middle, add the egg, stir until the two are combined then start gradually adding the milk and water combining as you go.

Add the liquid until the batter is a smooth and thin consistency.

Stir in half teaspoon of salt and leave to stand for 10 minutes

Put beef dripping into Yorkshire pudding tins or into one large tin but don’t use too much fat.

Put into hot oven until the fat starts to smoke.

Give the batter a final stir and pour into the tin or tins.

Place in hot oven until well risen – should take 10 to 15 minutes.

Serve

Always serve as a separate course before the main meal and use the best gravy made from the juices of the roast joint. Yorkshire housewives served Yorkshire pudding before the meal so that they would eat less of the more expensive main course.

NB: When the batter is made it must not be placed in the fridge but be kept at room temperature
