Best ever sliders with caper mayo

Happy Wednesday friends. The holidays may be quieter this year but I am still so busy! I received our holiday cards (see picture of the SB family at the beach last fall). Here is a holiday planning secret. I always order a regular Christmas card and a New Year’s card. That way I can send New Year’s cards to friends or contacts who may have sent us a card that was unexpected (or oops if I forgot someone!). It makes it look intentional versus sending a Christmas card after Christmas which always bothers my Type A personality. In all of the holiday busyness, I also realized that I had not yet shared Mr. SB’s recipe for his best ever sliders and amazing caper mayo from our Christmas tree cutting tailgate! Read on for the recipes, details, and here is the full tailgate post too.

Tips on making great sliders

It is not easy to get Mr. SB to reveal his secrets but I promise these are the most delicious sliders, and it was worth my cajoling (OK nagging) to get him to share his recipe. Here are a few of his tips too on making the best ever sliders with caper mayo.

First, try to buy locally sourced grass fed beef. We have a share with Walden Local which delivers monthly. This is not a sponsored post. From my experience with being a customer for over two years, I can assure you that their products are sustainable, grass fed (for the beef…they also offer seafood) and most importantly delicious. You do not have to worry about antibiotics or hormones in the meat as all of their meat comes from local farms that are strictly vetted. I also like knowing that the livestock is humanely raised. Ideally you will want 80% lean for the best sliders. Grass fed beef can be on the very lean side but what we buy from Walden Local has always made delicious sliders and burgers. If this sort of beef is not available, then simply buy the best quality you can at 80% lean.

Prepare the sliders ahead of time

Second, the sliders actually taste better if you prepare them a few hours in advance and refrigerate. The time allows for the spices to meld with the other ingredients. This is ideal for tailgating as you will want to have your burgers already mixed and formed into sliders.

Mr. SB always has a meat thermometer to test the right internal temperature. Frankly he prefers his meat on the rare side (that is very French) but with hamburgers I insist on well cooked as there is a risk of contamination. Check out the USDA’s link for what they recommend for safe cooking.

Toppings suggestions for sliders

He grills on his portable Coleman grill and once the sliders are done we always have an assortment of toppings – baby lettuce, ripe red tomato slices, thin onion for everyone to choose what they prefer. As for buns, we like ones that are firm enough that they are not impossible to eat when outside at a tailgate. Whole Foods always has a great selection in our area. Then of course, Mr. SB insists that the best topping is the caper mayo (and I have to agree…do not even suggest BBQ sauce as I did!). As the sliders are small, feel free to eat more than one. There is no point bringing home leftovers after a tailgate!
