You could easily do what you want with only async/await:

async function makePizza(sauceType = 'red') {
  // Spawn makeDough and makeSauce at "the same time"
  let doughTask  = makeDough();
  let sauceTask  = makeSauce(sauceType);  // Wait for both dough and sauce to be done
  let dough = await doughTask;
  let sauce = await sauceTask;  let cheese = await grateCheese(sauce.determineCheese());
  
  dough.add(sauce);
  dough.add(cheese);
  
  return dough;
}
