Heat the 4 Tbsp extra virgin Olive Oil in a heavy-bottomed saucepan over medium-high heat.
Add the 3-4 cloves fresh garlic, minced and continue to sauté for 3 minutes until fragrant (be careful not to burn the garlic) Stir often.
add the ½ Tbsp Red Pepper Flakes (more or less to your heat tolerance), and saute it for another minute to bloom the peppers.
Add the passata and stir to combine it with the olive oil until it is blended.
Add the 1 tsp sugar Let the sauce simmer on med-low heat for about 20 minutes before you use it. Stirring occasionally.
When the sauce has finished simmering and has reduced a bit, taste and adjust for seasonings. If the sauce still tastes acidic, try adding a pinch of baking soda or a pinch more of sugar. Once again taste and adjust as needed.
Add 3-4 leaves of fresh basil (Optional)
The sauce can be used immediately with your favorite pasta recipe or let it cool, place in a container and refrigerate and use within the next 5-7 days. Or it can be frozen for up to 3 months.
If freezing, I recommend putting the sauce into ice cube molds or large freezer cubes to freeze then once frozen pop them out of the trays and put in a freezer safe baggie, then just pull out as many "cubes" as you need.
