What’s the difference between Swiss roll and yule log?

Both Swiss roll and yule log are classic rolled cake desserts that are popular around the holidays. While they share some similarities, there are a few key differences between the two.

Origins

Swiss roll originated in Switzerland and England in the 19th century. It’s made by spreading a thin layer of sponge cake batter onto a baking sheet, covering it with jam, and then rolling it up into a log shape. The earliest published recipe for Swiss roll dates back to 1820 in England.

Yule log, or bûche de Noël, originated in France in the 19th century. It’s made by rolling up sheets of genoise sponge cake filled with chocolate buttercream to resemble a log. The cake is dusted with powdered sugar or coated in chocolate ganache. Yule logs are traditionally served around Christmas.

Ingredients

The main ingredients in Swiss roll are eggs, flour, sugar, and jam. It has a very light, tender crumb from the eggs and minimal flour. The filling is typically jam, though whipped cream is also popular. Swiss roll can be flavored with cocoa powder or extracts.

Yule log is made from eggs, flour, sugar, butter, and chocolate. It has a richer, denser crumb than Swiss roll due to the butter and extra egg yolks. The filling is usually chocolate buttercream, ganache, or whipped cream. Yule log often incorporates chocolate flavors throughout.

Swiss Roll Ingredients

  • Eggs
  • Flour
  • Sugar
  • Butter or oil (optional)
  • Jam, whipped cream, or cream cheese filling
  • Extracts or cocoa powder (optional)

Yule Log Ingredients

  • Eggs
  • Flour
  • Sugar
  • Butter
  • Chocolate (for cake and filling)
  • Heavy cream (for filling)
  • Ganache or icing

Texture

Swiss roll has a very light and tender crumb. It is meant to be delicate so it can be easily rolled up without cracking the cake. The texture is spongy from the whipped egg foams leavening the cake.

Yule log has a richer, denser crumb than Swiss roll. The addition of egg yolks and butter make it more moist and tender. It still maintains a soft crumb to allow rolling but is sturdier than Swiss roll.

Flavor

Swiss roll is lightly sweet with vanilla flavors. The jam filling provides a tart fruitiness to complement the cake. Some variations incorporate cocoa powder or extracts like almond, lemon, or raspberry.

Yule log has deep chocolate flavors both in the cake and filling. Common additions include coffee liqueur, almond extract, peppermint, or raspberry. The chocolate buttercream adds rich sweetness and intensity.

Shape

Both Swiss roll and yule log are rolled cakes baked in a flat sheet and filled before rolling up. This gives them both a distinctive round shape with spiral layers inside.

However, yule log is sometimes shaped and frosted to resemble an actual log. It may be coated in chocolate ganache or icing to mimic bark and dusted with powdered sugar for a snowy effect. Decorations like mushrooms or flowers are added for a forest theme.

Swiss roll typically maintains the round rolled shape without extra decoration. Some variations roll and slice the cake into pinwheel patterns first before finishing the roll.

Filling

Appearance

Swiss roll has a thin, golden yellow sponge cake texture. When sliced, the spiral layers of cake and filling are visible. The cake is rolled up into a round log shape.

Yule log is browned on the outside with lighter cake within. It looks like a tree log from its shape and bark-like chocolate coating. When sliced, the chocolate and cream layers create a visual contrast. Decorations add to the rustic log design.

Difficulty

Swiss roll is simpler to make than yule log. It uses fewer ingredients and requires less time and skill to execute. Since it calls for oil instead of butter, there is less risk of overmixing which can toughen the cake.

Yule log is more complex with its multiple components. Making the genoise sponge requires whisking the eggs and sugar properly to achieve the right airy texture. The buttercream also takes precision and coordination to make successfully without curdling. Decoration adds extra time and effort.

Swiss Roll Difficulty

  • Easy sponge cake recipe
  • Requires less baking precision
  • Minimal frosting skills needed
  • Easy assembly
  • Low risk of errors

Yule Log Difficulty

  • Genoise cake requires technique
  • Buttercream takes skill to perfect
  • Shaping and decorating adds challenges
  • More components means higher risk
  • Advanced baking and decoration skills

Time and Cost

Swiss roll is faster and cheaper to make than yule log. The simple cake takes about 30-40 minutes to bake and assemble. Ingredients like eggs, sugar, and jam are affordable basics.

Yule log requires more time and more expensive ingredients. Genoise and buttercream can take over an hour of active cooking time. Quality chocolate and heavy cream drive up costs. Decorations add to the budget as well.

Swiss Roll Time and Cost

  • Active time: 30-40 minutes
  • Inactive time: 10 minutes
  • Affordable ingredients like eggs, flour, sugar
  • Can be made for $5-$15 total

Yule Log Time and Cost

  • Decorations and components drive up price
  • Can cost $20-$50+ to make

Occasions

Swiss roll is enjoyed year-round for tea parties, birthdays, weddings, and other celebrations. It adds a light, festive touch to any dessert spread.

Yule log is primarily reserved for the holiday season, especially Christmas. It makes a dramatic centerpiece dessert for Christmas dinner or buffets. The log shape and decor evoke winter and the yuletide spirit.

Storage

Swiss roll is best consumed shortly after assembling since the cake can dry out and crack. It should be stored in the refrigerator no more than 2-3 days.

The chocolate and higher moisture content of yule log allow it to keep better than Swiss roll. It can be refrigerated 3-5 days when well wrapped. The chocolate also hardens when chilled for cleaner slicing.

Swiss Roll Storage

  • Best eaten same or next day
  • Keeps 2-3 days refrigerated
  • Dries out quickly
  • Cracking and unraveling risk

Yule Log Storage

  • Keeps 3-5 days refrigerated
  • Chocolate hardens when chilled
  • Less staling due to higher moisture
  • Wrapping well prevents drying
