Method

• Make the dough: In a small bowl, combine the warm water, yeast, and sugar. Let stand for 5 minutes, or until the yeast is foamy.
  
  
• In a large bowl, whisk together the olive oil, flour, and salt.
  
  
• Add the yeast mixture to the dry ingredients and stir until a dough forms.
  
  
• Turn the dough out onto a lightly floured surface and knead for 5-7 minutes, or until smooth and elastic.
  
  
• Place the dough in a greased bowl, cover with plastic wrap, and let rise in a warm place for about 1 hour, or until doubled in size. 
  
  
• Punch down the dough and divide it into small pieces, about the size of a walnut. 
  
  
• Heat about 1 inch of oil in a deep fryer or large pot to 350°F (175°C).
  
  
• Fry the dough balls in batches for 2-3 minutes per side, or until golden brown.
  
  
• Remove the tullumba from the oil and drain on paper towels.
  
  
• Make the syrup: In a small saucepan, combine the water, sugar, lemon juice, and vanilla extract. Bring to a simmer and cook for 5-10 minutes, or until the syrup thickens.
  
  
• Soak the tullumba: Dip the warm tullumba into the syrup and let them soak for a few minutes.
  
  
• Top with nuts and cinnamon: Roll the soaked tullumba in a mixture of chopped nuts and cinnamon.
