Sumac baked sweet potatoes cut into fries

I’ve been hearing a lot about the spice Sumac the past few months. It’s a Middle Eastern spice that is tangy with a hint of lemon and not at all spicy. It can be used in so many ways to season meat and fish, add to hummus and  season vegetables to add a delicious bright flavor.  

Today, we are making some seasoned baked fries and certainly not forgetting the dip. The dip is a cool and refreshing yogurt mint dip with a hint that is a delicious complement to the lemon sumac flavor and sweet potatoes.

For the potatoes I’m using orange and white sweet potatoes for a colorful presentation.  Most people call the orange potatoes sweet potatoes but they are in fact yams. The white potatoes I used are sweet potatoes, but they’re both sweet and both potatoes, so I am now calling them both sweet potatoes (no need to split hairs here).

Lets talk about the cornstarch used on the potatoes, it’s not just a thickener for sauces. Cornstarch is added to fried chicken batter to make it really crispy and the same is applied here. Sweet potatoes need a little help getting crispy in the oven and coating the potatoes in cornstarch helps achieve the best crispiness we can get. It wont make them as crispy as regular potatoes.

If you’re wondering where to find this amazing sumac spice, I  haven’t started seeing sumac in my regular grocery store, but it is available at Whole Foods and Amazon.
