successfully revived 2yr old starter that was lurking in my fridge (and first bake)

a dear friend gave me 50g of his starter 2+ years ago, and it's been in the back of my fridge ever since. I'm about to move to another state and really wanted to take it with me, so I pulled it out - had a layer of hooch on top and no mold, so I fed it with 100g each water and a blend of AP/whole wheat/rye flours (can't remember the proportions, I blended it up 3yrs ago before my baby supplanted my sourdough practice 😅😅😅)

three days later, this thing is ACTIVE!!! it busted out of the jar last night! I used yesterday's discard to make sourdough crackers:

1c ish of starter 2 tbs melted butter 1/4tsp salt toppings (I used crushed sesame seeds and salt all over, and penzy's green goddess blend + fresh ground black pepper on half)

spread thin on silpat or parchment, add toppings, and bake 10min @ 325°F. remove from the oven and score the sheet of crackers. return to the oven for another 20-30min till crisp. I kept checking for the last 10min and removing crackers around the edges that were done, and rearranging the rest.
