Instructions for Pastry Cream for two 8 inch tarts:

  1. Weigh sugar and yolks into TM bowl; insert butterfly and whisk until voluminous and light in colour for 1 minute at speed 4, scraping down sides of bowl with butterfly and repeat once (maybe twice)

  3. Scrape down sides with spatula; mix to combine for 5 seconds at speed 3

  4. Weigh milk and vanilla paste into TM bowl; cook and whisk for 6-7 minutes at 90C on speed 4 (depending upon temp of milk; if room temp, 5.5 minutes) AS SOON AS TEMP reaches 90C, increase temp to 110 and time to 5.5 minutes to ensure mixture boils for 2 minutes

  5. Remove from heat and immediately strain through fine mesh to remove lumps into a second TM bowl, whisk attached, if you have one, or into a separate bowl; clean TM bowl and return ingredients back into the bowl

  3. Cover surface with plastic wrap and chill 3-4 hours before use
  4. Cream will be very thick and set when removed from refrigerator; stir to silken or desired consistency before using

Recipe Notes

Chef Pattie explained that as egg proteins coagulate at 85 C, the starch granules don’t reach their full thickening potential until they come to the boil, therfore the temperature must be increased to 110C for 2 minutes of boiling time for best results. The time is dependent upon ingredients going into the machine. Time varies considerably for room temperature ingredients going into the TM bowl vs fridge temperature ingredients.

Ingredients need to boil at least a minute, preferably 2 and not more.
