Pound Cake Adapted from Cook's Illustrated - Metric

I love Cook's Illustrated but can't understand why they don't publish metric measurements alongside imperial. Also, I prefer to weigh ingredients because it's so much easier.


500g butter
3 large eggs
3 large egg yolks
2 teaspoons vanilla extract
200g self raising flour (CI use plain flour)
½ teaspoon table salt
250g sugar (1¼ cups)


 1.      Cut butter into 1-tablespoon pieces and place in bowl of standing mixer; let stand at room temperature 20 to 30 minutes to soften slightly (butter should reach no more than 15 degrees celcius).
2.      Using a fork, beat eggs, egg yolks, and vanilla in liquid measuring cup until combined. Let egg mixture stand at room temperature until ready to use.
3.      Adjust oven rack to middle position and heat oven to 160 degrees celcius.
4.      Generously butter 9 by 5-inch loaf pan; dust pan liberally with flour and knock out excess.
5.      In standing mixer fitted with flat beater, beat butter and salt at medium-high speed until shiny, smooth, and creamy, 2 to 3 minutes, scraping bottom and sides of bowl once with rubber spatula. 
6.      Reduce speed to medium; with mixer running, gradually pour in sugar (this should take about 60 seconds).
7.      Once all sugar is added, increase speed to medium-high and beat until mixture is fluffy and almost white in color, 5 to 8 minutes, scraping bottom and sides of bowl once.
8.      With mixer running at medium speed, gradually add egg mixture in slow, steady stream; this should take 60 to 90 seconds.
9.      Scrape bottom and sides of bowl; beat mixture at medium-high speed until light and fluffy, 3 to 4 minutes (mixture may look slightly broken). Remove bowl from mixer; scrape bottom and sides.
10.   In 3 additions, sift flour over butter/egg mixture; after each addition, fold gently with rubber spatula until combined. Scrape along bottom of bowl to ensure that batter is homogenous.
11.   Transfer batter to prepared loaf pan and smooth surface with rubber spatula.
12.   Bake until golden brown and wooden skewer inserted into center of cake comes out clean, about 70 to 80 minutes.
13.   Cool cake in pan on wire rack for 15 minutes; invert cake onto wire rack, then turn cake right side up.
14.   Cool cake on rack to room temperature, about 2 hours. Slice and serve.
